DID A DINGO REALLY GET HER BABY?

A10Azaria Chamberlain—a nine-week-old infant—disappeared from her family’s campsite at Ayers Rock (now called Uluru) in the central desert of Australia’s Northern Territory on August 17, 1980. Despite a massive search, Azaria’s body was never found and the question of whether she was taken from the tent by a wild dog or whether she was killed by her mother, Lynne (Lindy) Chamberlain, lingered on.

Lindy Chamberlain was charged with Azaria’s first-degree murder and convicted of her daughter’s slaying. After thirty-two years, eight legal proceedings, and tens of millions spent in the investigation, Lindy was finally exonerated by a coroner’s inquest that declared Azaria’s death was an accident—the result of a wild animal attack, to wit—a dingo.

The case was entirely circumstantial and supported by incriminating points of forensic evidence that convinced a jury to find Lindy Chamberlain guilty beyond a reasonable doubt. But how credible were these “forensic facts”? Where did the case go wrong? And what led to Lindy’s conviction being overturned?

A3Lindy Chamberlain, 34, her husband Michael, 38, son Aidan, 6, son Reagan, 4, and infant Azaria were on a family vacation and pitched their tent in the Ayers Rock public campground at the famous World Heritage site. At eight p.m. and well after dark, Lindy finished breast-feeding Azaria and took her to the tent—thirty feet from the picnic table where she placed the baby in a bassinet and covered her with blankets. She’d taken Aidan with her and Reagan was already asleep inside.

Lindy went to their car that was parked beside the tent and got a can of baked beans to give Aidan as a bed-time snack, then returned with Aidan to Michael at the picnic table. At 8:15 p.m Azaria cried out. Concerned, Lindy walked toward the darkness of the tent-site and claimed she saw a dingo at the opening of the unzipped tent door. It appeared to have something in its mouth and was violently shaking its head.

Lindy hopped a short parking barricade which made the animal flee into the night. She checked inside the tent.  Azaria was gone and there were fresh blood stains on the floor, bedding, and other articles. Lindy rushed out, yelling to Michael and the other campers “Help! A dingo’s got my baby!

A19The adjacent campers formed a search party which was re-enforced by authorities and local residents, eventually totaling over three hundred volunteers including Aborigine expert trackers with their dogs. Dingo paw prints were noted in the sand outside the tent and a trail was followed which showed marks indicating a dingo was partly dragging an object, periodically setting it down to possibly rest or readjust its grip. (Azaria weighed just under ten pounds.) The trail indicated its destination was toward known dingo dens at the southwest base of Ayers Rock.

By daylight, no sign of the infant was found and the search was called off. The Chamberlain family cooperated in a preliminary investigation conducted by police from the nearest town of Alice Springs, then they returned home to Mount Isa.

A4Initially, there was no doubting the Chamberlains’ story. A dingo was seen in the campground before dark by campers. Others heard a dog growl minutes prior to the baby’s cry. They also heard Lindy’s scream “A dingo got my baby!” Further, the park ranger had warned that the dingo population was increasing and becoming very aggressive. And young Aidan backed up his mother’s story of going to the tent and the car, being with Lindy throughout.

The police investigation stopped. But, seven days later, a hiker found some of the garments Azaria was dressed in, nearly three miles away by the dingo dens. The clothes were a snap-buttoned jumpsuit, a singlet, and pieces of plastic diaper, or “nappy” as they say in Australia. Still missing was a “matinee” coat that Azaria wore overtop.

A17The examination found bloodstains on the upper part of the jumpsuit which showed a jagged perforation in the left sleeve and a “V”-shaped slice in the right collar. The singlet was inside out and the diaper fragments were shredded. The police officer who retrieved the garments failed to photograph their original position as had the original police officers attending the incident failed to photograph the scene. They also failed to properly examine and photo the tent’s interior which others reported was pooled and spotted with blood.

By now the Dingo’s Got My Baby case was getting international attention and the speculative rumor mill was alive in the media. “Dingos don’t behave like that!” self-appointed experts were saying. “It’s unheard of for a dingo to do this!” “Dingos can’t run with something in their mouths!”

A15Bigotry was emerging because the Chamberlains were Seventh Day Adventists with Michael being a professional pastor. “They’re a cult!” “They believe in child sacrifice!” “They were at Ayers Rock for a ritual!” “They always dressed the baby in black!” “The name ‘Azaria’ means ‘Sacrifice in the Wilderness’!”

When the first inquest was held in February, 1981, the media was in a frenzy and the police were covering their butts. The coroner ruled Azaria’s death was due to a dingo attack, despite there being no physical body to examine, and was critical of shoddy police investigation and of certain government officials of the Northern Territory who failed to provide the police with resources to investigate.

This threw fuel on the media fire and caused the authorities to start damage control.

A7A task force was formed to re-open the case, fittingly named Operation Ochre after the red sands of Ayers. It was headed by an ambitious police Superintendent with an aggressive field detective and was overseen by a politically-protective prosecutor. Collectively, they ran the investigation with the mindset that the dingo attack was implausible and that Lindy fabricated the story because she’d killed her own kid.

On September 19, 1981, Operation Ochre did a massive round-up of the original witnesses for re-interviews and raided the Chamberlains’ home. They seized boxes of items in a search for forensic evidence and impounded their car.

The investigation theory held that Lindy took Azaria from the tent to the car where she slit her baby’s throat, then stuffed her infant’s body in a camera bag. With husband Michael’s help, and after the searchers went home, they took their daughter’s body far away to the dingo dens, buried their little girl, then planted her clothing as a decoy.

There wasn’t the slightest suggestion of motive or any consideration of how the Chamberlains were stellar in reputation.

A6The vehicle was forensically grid-searched over a three-day period by a laboratory technician with a biology background. Suspected bloodstains were found on the console, the floor, and under the dashboard which was described as at trial as an “arterial spray” pattern.

Blood was also found on various items taken from the Chamberlains’ home, known to be present in the tent at the time Azaria disappeared. The lab-tech confirmed the blood on Azaria’s jumpsuit was not only human—it was composed of 25 % fetal hemoglobin which was consistent with an infant’s blood.

This was the forensic cornerstone of the prosecution’s circumstantial case.

A8A second inquest was held in February, 1982. It was run as a prosecution—an indictment with the focus on proving a theory, rather than discovering facts. The Chamberlains were not privy to the “evidence” beforehand and had no ability to defend themselves. “Information” was presented by the lab-tech that blood from the car was consistent with fetal hemoglobin and, therefore, the baby must have bled out in the car.

Another forensic expert testified the cuts and bloodstain pattern on the jumpsuit were caused by a sharp-edged weapon, probably a pair of scissors, and were in no way caused by canine teeth.

Despite all the civilian witnesses testifying consistently as before, and corroborating the Chamberlains claims, the inquest deferred judgment and referred the case to the criminal courts.

A12

Lindy was tried for Azaria’s murder in September, 1982, and her husband was accused of being an accessory-after-the-fact. Over a hundred and fifty witnesses testified, many of those being forensic experts—some of considerable note. The Chamberlains were forced to defend themselves, funded by their church and donations by believers in their innocence. They had no access to disclosure of evidence by the prosecution and were kept on the ropes by surprise after surprise of technical evidence which they had no time nor ability to prepare a defense.

A20This trial was not just sensational in Australia. It was carried by all forms of world news—TV, radio, print, and tabloids. As big as the O.J. Simpson trial would become in America, the public were split on the question of Lindy’s guilt or innocence.

The jury bought the prosecution’s case that science was far more reliable that eye and ear witness testimony and the Chamberlains were convicted. Lindy was sentenced to life imprisonment with hard labor and Michael was given a three-year suspended sentence. A pregnant Lindy went directly to jail where their newest baby—a daughter—was born. Two appeals to Australian high courts fell on deaf ears. They found no fault in the application of law.

The Dingo Got My Baby case never faded from public interest. Many groups petitioned, calling for changes in the law and for a new, fair trial to be held. Pressure mounted on the Australian Northern Territory officials.

A18On February 02, 1986, a British rock climber fell to his death on Ayers Rock. During the search for his body, Azaria’s missing matinee jacket was found—partially buried in the sand outside a previously unknown dingo den. The examination found matching perforations in the coat consistent with the jumpsuit cuts.

News of this find caused a massive public outcry against the Northern Territory government and they reluctantly released Lindy from jail pending a re-investigation. A third inquest was a “paper” review that recommended the matter be sent back to the courts.

A Royal Commission of Inquiry into Lindy Chamberlain’s conviction was held from April, 1986, to June, 1987. It focused on the validity of the scientific evidence, rather than on legalities of court procedure.

A21The jewel of the forensic crown—the fetal hemoglobin in the family car bloodstains turned out not to be blood at all. The drops were spilled chocolate milkshake and some copper ore dust while the “arterial spray” was overspray from injected sound deadener applied at the car’s factory.

The clothing cuts became an Achilles’ Heel and toppled the case because the expert witness by now was discredited in other cases resulting in wrongful convictions. New forensic witnesses, with more advanced technological expertise, testified the cuts were entirely consistent with being mauled by a dog.

In September, 1988, the Australian High Court quashed the Chamberlains’ convictions and awarded them $1.3 million in damages—far less than their legal bills, let alone compensating their pain and suffering.

A1The High Court never said Lindy was innocent, though. It rightfully set aside her conviction but made no amends in publically proclaiming innocence.

It wasn’t until 2012, that Lindy’s perseverance forced the fourth inquest. The presiding coroner classified Azaria Chamberlain’s death as accidental—being taken and killed by a dingo.

Coroner Elizabeth Morris had the decency to publically apologize to Lindy on behalf of all Australian authorities for a horrific, systematic miscarriage of justice.

Coroner Morris also had the class not to single out individuals. Without her saying, it was evident the police, prosecution, and forensic people instinctively reacted as they’d been trained to react—and that was to individually find evidence to support their case interest and not to follow what didn’t fit.

And Coroner Morris was careful not to burn the media.

A23Lindy’s situation was a media dream, having all the elements of a thrilling novel—mystery, instinctive fears, motherhood, femininity, family, religion, politics, and an exotic location combined with courtroom and forensic drama.

And it came at the expense of an innocent human mother who’s baby girl got taken by a wild animal—probably a mother dingo instinctively trying to feed her own family.

SOLVING THE 5,000-YEAR-OLD MURDER OF “OTZI THE ICEMAN”

A7In 1991, the mummified body of a 5,000-year-old murder victim was discovered in melting ice at a rock-gully crime scene high in the Italian Otzal Alps. Nicknamed “Otzi”, the estimated 45-year-old man and his possessions were incredibly well preserved. His skin, hair, bones, and organs were cryopreserved in time, allowing archeological researchers a phenomenal insight into human life in the Copper Age.

The frozen-in-time corpse also gave modern science the opportunity to forensically investigate and positively determine how Otzi The Iceman was killed.

A44On a sunny September day, two hikers were traversing a mountain pass at the 3210 meter (10,530 foot) level and saw a brown, leathery shape protruding from the ice amidst running melt-water. Closely examined, it was a human body which they thought might be the victim of a past mountaineering accident.

They reported it to Austrian police who attended the following day and quickly realized they were dealing with an ancient archeological site. A scientific team was assembled and, over a three-day period, the remains were extracted and taken to the Institute of Forensic Medicine in Innsbruck.

B9Such an incredibly valuable find soon led to a jurisdictional argument between the Austrian and Italian governments and an immediate border survey was done, finding Otzi had been lying ninety-two meters inside of Italian territory. Italy gained legal possession of the body and artifacts, however in the interests of science and history, everything was kept at Innsbruck until a proper, climate-controlled facility was built at the South Tyrol Museum of Archaeology in Bolzano, Italy, where Otzi the Iceman now rests.

Many, many questions arose. Who was he? Where did he come from? How long ago did he live? And, of course, what caused his death?

Technological advances over the past twenty-five years have answered some questions surrounding Otzi’s life and death and surely the next twenty-five will answer more. This, so far, is what science knows about the Iceman.

A6Otzi was found lying face down with outstretched arms in a protected, rock depression near the Finail Peak watershed at the top of the Tisenjoch pass which connects two forested valleys. The trench measured 40 meters (131 foot) long, between 5 and 8 meters (16–26 foot) wide, and  averaged 3 meters (10 feet) deep. For millennia, this area was covered by glaciers which, by the end of the twentieth century, had receded.

Four separate scientific institutes conducted C-14 radiocarbon dating on Otzi, equivocally agreeing he came from between 3350 and 3100 BC — more than 5,000 years ago. This was the oldest-known preserved human being; far older than the Egyptian and Inca mummifications or the corpses found pickled in peat bogs.

A8Something exceptionally unique about Otzi was that he was a “wet” mummy—an almost unheard of process for a cadaver of this age where humidity was preserved in his cells, unlike the intentional dehydration processes used in Egypt and Peru. As well, Otzi was perfectly intact and not dissected or embalmed by a funeral ritual. His entire body achieved a state of elasticity and, although shrunken, remained as in the day he died including vital clues stored in his digestive tract.

Researchers felt Otzi must have been preserved through a chain of coincidences. It was evident that no damage had been done by predators, scavengers, or insects so it was obvious that the body was covered by snow and/or ice immediately after death. Secondly, the gully lay perpendicular to the main ice flow, allowing the grinding action of the glacier to pass overtop. Thirdly, exposure to air and sunlight was only a brief period before being found by the hikers.

It was vital Otzi remain frozen to avoid an irreversible decomposition and remain intact to preserve his historical significance. This gave researchers limited ability to examine the cadaver as would be done in a conventional autopsy.

B3A thorough external exam was done in 1991 along with Xray radiography images. Notable was a cut to the back of the right hand which showed early signs of healing as well as breaks to the left ribcage, which had healed, and breaks to the right ribs which were fresh at the time of death. A depression in the skull was thought to be caused by the weight of ice compression and analysis of the only remaining fingernail found that the Beau-Reil Lines, which are like rings on a tree trunk, showed significant stress to his immune system in three periods—16, 13, and 8 weeks before death.

A46Other factors told of Otzi’s failing health—understandable for a 45-year-old in the Copper Age who’d then be considered elderly. He suffered from tooth decay, gum disease, and worn joints. What shocked the researchers were the amounts, designs, and placement of tattoos on Otzi’s body. There were 61 separate markings, all made by incisions and insertion of charcoal—not ink as has been used by other cultures for centuries. The locations were consistent with known acupuncture points as practiced for pain relief thought to be discovered by the Chinese two thousand years after Otzi’s existence. It seemed these markings were therapeutic, rather than symbolic.

Despite examination by many leading experts, no exact cause of Otzi’s demise was determined and it was speculated this old man may have fallen, injured himself, then succumbed to the elements. That was until new technology was developed.

A47One of the great challenges was to examine Otzi endoscopically—that is to look internally at his organs. Special high-precision titanium instruments were invented—steel probes that were inserted through tiny incisions in Otzi’s back. Using computerized navigational aids, the tools were guided to exact spots were evidentiary samples could be taken. This was recorded with a hi-definition camera and an entire 3-D map of the mummy’s thorax and abdomen was made.

Lung and digestive tract contents told a time-of-year travel story through the presence of thirty different pollens which entered Otzi’s body by the food he ate, the water he drank, and the air he breathed.

A48Most pollens were from trees and indicated he ingested them during a bloom in the late spring or early summer. The locations and digested states of different pollens in different sections of the stomach and intestines showed Otzi had made a climb from the valley floor to the top of the pass where he died within a twenty-four hour period. Pollens in the lower gastrointestinal tract were identified to low elevation trees and pollens in the upper GI were from higher elevation species.

So, it was known that Otzi had left the populated valley and headed for high country where he met his death. Speculation rose that he might have been fleeing some danger.

A3This theory strengthened in 2001 when new Xrays identified a small, flint arrowhead in Otzi’s left shoulder which was missed ten years earlier. A close examination of Otzi’s back revealed a two-centimeter slash and established the arrow’s path. He’d been shot from a rear and lower position.

In 2005, Otzi was put through a high-resolution, multi-slice CT scanning machine which enlightened the arrow wound. Clearly, the arrowhead had caused a one-centimeter gash in Otzi’s left subclavian artery which is the main circulatory pipeline that carries fresh oxygenated blood from the heart to the left arm. Such a serious tear would have caused massive internal bleeding and rapid death—probably within two minutes.

A49The CT scan showed something else. There was serious bleeding at the base of the brain which corresponded to the depression in Otzi’s skull. He’d suffered a serious head injury right at the time of death. With the cause of death now certain to be from a violent act of homicide, the prime question centered on the circumstances of how all this went down.

Researchers felt the answer may lay in the Iceman’s possessions.

A50Among the artifacts found on and around Otzi’s body were a copper ax, a flint dagger, a quiver with twelve blank arrow shafts and two completed arrows with stone heads. There was also winter clothing and supplies to support wilderness survival.

This speaks to motive, for if robbery was behind Otzi’s murder, it’s certain that the perpetrator(s) would have made off with these valuables. Glaringly missing was the shaft of the fatal arrow, especially in light of Otzi’s quiver arrows being perfectly preserved.

A51Egarter Vigl, a leading archeological expert on the Iceman, believes that the assailant tried to pull out the fatal arrow to destroy evidence, only to snap off the arrowhead inside. Vigl was quoted in the archeology magazine Germani, “telltale markings in the construction of prehistoric arrows could be used to identify the archer much in the way modern ballistics can link a bullet to a gun. The killer yanked out the arrow to cover his tracks. For similar motives, the attacker did not run off with any precious artifacts that remained at the scene, especially the distinctive copper-bladed ax; the appearance of such a remarkable object in the possession of a villager would automatically implicate its owner of the crime.”

I’d have to agree with Mr. Vigl, and I’d like to add an observation of my own.

A33In the hundreds and hundreds of dead bodies I’ve examined as a cop and a coroner, I’ve never seen a cadaver with its arms outstretched in a hyperextended position like how Otzi the Iceman was found. This is absolutely unnatural and shrieks to me that someone placed the arms in that position after death.

I think it’s safe to speculate on what might have happened and here’s what Otzi’s crime scene evidence suggests to me.

A52The day before Otzi’s death, he was in a physical altercation down at the village on the valley floor where he suffered the cut hand and possibly the broken right ribs. This caused him to pack up and flee, climbing to the elevated pass where he was overcome by his attacker(s) and shot with the arrow from behind and below. This wound would have put Otzi into hemorrhagic shock and he would have quickly collapsed and internally bled out. Following his collapse, the murderer(s) went up and caved-in the back of Otzi’s head to finish him off.

I don’t think this happened in the gully. I’ve looked at the scene photos and can’t envision how Otzi could have been shot from below in that tight gully, which is what the forensic evidence clearly shows on the arrowhead’s track through the body—even if Otzi were bending over.

A53No, I suspect Otzi was shot elsewhere, dragged by the arms, dumped in the gully with all his possessions, rolled over to remove the arrow, and then covered with ice and/or snow to hide the crime.

After 5,000 years, the answers to “By who?” and “For what reason?” are unlikely to be known—despite what future technology might bring—and the murder of Otzi the Iceman will always remain a really cold case.

GENOMICS — THE FUTURE OF FORENSIC DNA PROFILING

A3Genomics is the scientific study of the molecular instructions encoded in your cells.  It maps your entire genetic structure. Till now, forensic science has focused on only identifying your cell’s nuclei signature — your inner DNA (deoxyribonucleic acid) and, to a degree, your outer miDNA (mitochondrial DNA) — not your genes. The old method of forensically profiling your biological fingerprint by DNA analysis is being replaced by a computerized 3D genome recreation of your entire being.

A17Genomics is a concept first developed in the 1970’s. It led to the Human Genome Project (HGP) being completed in 2003. The HGP was a massive international research venture that sequenced and mapped all of the human cell genes — together known as the genome. The HGP gave us the ability to read nature’s complete genetic blueprint for building a human being. Like you.

So what’s a genome?

A14A genome is the whole ensemble of your genetic material. It’s the molecular guide of your DNA, your chromosomes, and your genes that tells how to make your cells. It’s the instruction manual for your body. That book is your genome and the study of that book is termed genomics. It’s pretty much a math exercise. And it’s deadly stuff for identifying criminals with.

Let’s take a quick look at your biology.

A35Deoxyribonucleic acid is the chemical compound that contains the instructions to develop and direct your life as an organism. DNA molecules are made of two twisting, paired strands, often referred to as a double helix.

Each DNA strand is made of four chemical units, called nucleotide bases, which comprise the genetic “alphabet.” The bases are adenine (A), thymine (T), guanine (G), and cytosine (C). Bases on opposite strands pair specifically — an A always pairs with a T — a C always pairs with a G. The order of the As, Ts, Cs, and Gs determines the meaning of the information encoded in that part of a DNA molecule. It’s just like the order of letters determine the meaning of a word, only DNA is written out in a barcode locus.

Every single cell in your body contains a complete copy of the 3.2 billion DNA base pairs, or letters, that code your human genome.

DNA’s four-letter language contains information needed to build your physical body. A gene refers to the unit of DNA that carries the instructions for making a specific protein, or set of proteins, and there’s 23,000 genes in your genome code. Each gene directs an average of three proteins.

A11

If you could peer inside your cells, you’d see your genome contained in 46 tightly packed bundles of DNA — 23 came from your mother and 23 from your father. These DNA bundles, called chromosomes, provide instructions that enable a one-cell embryo to develop into a 100 trillion-cell adult. So, every time the human body produces a sperm or an egg, 3 billion DNA letters must be copied and packaged so they can be passed along to future offspring.

A31Humans come in many shapes and sizes, but we’re all very similar at the DNA level. In fact, the genomes of any two people are more than 99% the same. Still, the tiny fraction of the genome that varies among humans is critical when it comes to forensically identifying a particular individual. DNA variations are part of what makes each of us unique, but it’s in the genes that the real difference lies. They direct what you look like.

Okay. Enough of the biology lecture. How is genomics gonna catch some crooks?

It’s not just genomics. Science now has a great handle on how your DNA is formed and how your genes fine-tune your uniqueness. The problem has been in how to process a staggering forensic workload that has bottlenecked the crime labs and the courts — and how to put a face and a name to an unidentified DNA profile..

A26The answer lies in genomic computerization. The good news is that technological progress is being made faster than anyone ever dreamed possible. Now the labs are looking at your entire genome package for identification, not just at that little bit of nucleic or mitochondrial DNA which is dirty, volatile, and time-consuming stuff to process.

Advancements in computerized processing are allowing crime labs to build an entire picture of you as a suspect — not just an impersonal, academic graph of the matching points in either your biological evidence sample that you left behind at the scene, or your known reference sample that investigators obtained from you.

A2Think about how many cold cases there are where the investigators have a clear DNA profile of you as the perpetrator, but they have absolutely no clue what you look like. They have no idea whether you’re young or old, black or white, have green eyes or brown. They don’t know your hair color or texture. They don’t know if you’re tall or short. And, in some cases, they don’t know if you’re male or female.

Genomic profiling is going to change the game. Computers will speed it up. 

A25Illumina Corporation of San Diego is a world leader in Forensic Genomic technology. They’ve developed a process called Next Generation Sequencing (NGS) that can simultaneously analyze every locus-point in a traditional DNA barcode using less than 1 nanogram of a sample in a fraction of traditional turn-around time that it’s currently taking.

Illumina is also at the forefront of developing the new cornerstone of contemporary forensic science — being able to generate a physical description of the DNA’s donor based on their genome profile.

A22Think about the ramifications. It’s not only going to assist in solving current cases. It’s going to give a physical look at the perpetrators of cold cases. Identify found remains with no names. Help in sorting disaster victims. And make accurate aging estimations for missing children.

The speed and accuracy of forensic genomic profiling will have far reaching effect on the costs in the criminal justice system. Faster and higher rates of identification will remove more dangerous offenders from society and the reliability of their forensic identifications will result in less trial time. It will reduce investigator workload in chasing blind leads. And it will, undoubtedly, save lives.

A29I think we’re in a fascinating time, watching technological advancements in forensic sciences. Genomic profiling is a fantastic breakthrough. We’re close to the day when your tiny biological dropping at the scene of your crime will go into a machine, the button pressed, and not just will your virtual mugshot come out — it’ll build a full-color, 3D image of your entire person right from your molecules to your moles.

Yes, science has come a long, long way in understanding how your human genome instruction book is written.

God knows who wrote it.
