Manufacturing Guilt
Experts say an exclusive video shows a dental examiner
creating the bite marks that put a man on death row.

Editor's Note: The following article
contains graphic and disturbing photographs of an examination conducted
on the body of a 23-month-old girl. The images are the basis of claims
that forensic experts fabricated evidence in a case that put a man on
death row, where he awaits exoneration or execution.
For most of the last 20 years, doctors Steven Hayne and Michael West
have served as expert forensic witnesses for the state of Mississippi.
Until 2008, Hayne served as the de facto state medical examiner,
dominating a criminal autopsy market in which prosecutors contract out
examinations to favored private doctors. West, a dentist, served one
term as the elected coroner in Forest County, Mississippi in the 1990s
and partly through his work with Hayne became a popular bite-mark
examiner among prosecutors. Both men have come under intense scrutiny
for questionable working procedures and dubious testimony—West off and
on for 15 years, Hayne mostly in the last two. Reason has been
following Hayne's deteriorating career since an October 2006 article
that detailed his role in putting a possibly innocent man named Cory
Maye on death row (see an archive of our Hayne-related reporting at:
www.reason.com/hayne).
Last year, two men that Hayne and West helped convict of murder in the
early 1990s, Levon Brooks and Kennedy Brewer, were exonerated and freed
from prison through DNA testing after serving more than 30 years
combined behind bars. Both men had been accused of raping and murdering
the daughters of their respective girlfriends. In what has come to be a
pattern with the two doctors, in each case Hayne claimed to have found
in an initial autopsy what other examiners missed: bite marks on the
victim's body. He then called in West, a forensic odontologist (dental
examiner), who definitively matched bite marks to the defendants.
Partly because of the testimony from Hayne and West, Brooks was
sentenced to life in prison, and Brewer to death (he spent 14 years on
death row). DNA testing in 2008 determined that the semen found on both
girls belonged to a third man, 51-year-old Albert Johnson. As Brooks
and Brewer were freed, Johnson confessed to both crimes.
The Brooks and Brewer cases form their own forensics riddle: How could
West and Hayne have definitively linked previously undetected bite
marks on the victims to two men who didn't commit the murders?
Reason recently obtained shocking video from another Hayne and West
collaboration that may shed light on the question. In 1993, the two
conducted an examination on a 23-month-old girl named Haley Oliveaux of
West Monroe, Louisiana, who had drowned in her bathtub. The video shows
bite marks mysteriously appearing on the toddler's face during the time
she was in the custody of Hayne and West. It then shows West repeatedly
and methodically pressing and scraping a dental mold of a man's teeth
on the dead girl's skin. Forensic scientists who have viewed the
footage say the video reveals not only medical malpractice, but
criminal evidence tampering.
How Jimmie Duncan Landed on Death Row
Haley Oliveaux did not have a happy young life. Her mother was
divorced. Her father was in prison. In November 1993, she was twice
taken to the hospital after suffering seizures. On November 29 of that
year, she was again admitted to the hospital, this time after allegedly
pulling a chest of drawers down on top of herself while climbing to
reach for a piggy bank. She suffered multiple skull fractures in the
incident and, notably, some bruising on her left elbow. An
investigation by the West Monroe Police Department and Ouachita Parish
Child Protective Services found no evidence of abuse and no reason to
doubt the piggy bank story.
Three weeks later, on December 18, Allison Oliveaux went to work at
8:45 a.m., leaving Haley in Jimmie Duncan's care. According to Duncan,
he gave Haley a bath later that morning, and left her in the bathtub
while he washed some dishes. At around 10:30 a.m., Duncan said, he
returned to the bathroom to find her lying motionless in the tub.
Duncan said he rushed Haley to the house next door, where neighbor
Floyd Bennett tried to administer CPR while his son called an
ambulance. The ambulance crew described Duncan as hysterical and
weeping. Haley was taken to the hospital, and pronounced dead shortly
thereafter. After admitting to the police that he'd left Haley alone in
the tub, Jimmie Duncan was arrested and charged with negligent
homicide, or criminal inaction leading to another person's death.
But after the autopsy and examination by Hayne and West, prosecutors
raised the charges. Citing the bite-mark analysis, along with other
evidence, prosecutors charged Duncan with capital murder, alleging that
he raped Haley Oliveaux in the bathtub, forced her head underwater, bit
her, and drowned her. Five years later, even though the only physical
evidence directly linking him to the girl was the bite-mark analysis,
Jimmie Duncan was tried, convicted, and sentenced to death. He has been
on death row in Louisiana for 10 years.
Louisiana had its own medical examiners at the time who were closer to
the scene of the crime. Nonetheless, Haley Oliveaux's body was taken
from Glenwood Regional Medical Center in West Monroe, Louisiana, 120
miles east to Jackson, Mississippi, so it could be autopsied by Hayne.
At the time, Hayne, who has never been certified in forensic pathology,
was performing the majority of autopsies in Mississippi, some
1,200-1,500 per year. That's an output other forensic pathologists
describe as impossible (he was also holding down two hospital jobs and
testifying regularly in court).
Despite his heavy workload in Mississippi, Hayne, with West by his
side, began looking for business in Louisiana, too. In October 1993,
the Baton Rouge Advocate reported that officials in Ouachita Parish
(where West Monroe is located) were considering sending criminal
autopsies to Hayne, despite concerns expressed by other medical
examiners about the quality of his work. Oliveaux was one of Hayne's
first autopsies for Ouachita Parish, according to testimony from
Duncan's trial. Among those who traveled 120 miles to observe the
examination were the West Monroe police chief, a police detective and
captain, plus two assistant district attorneys. Though it isn't
particularly unusual for a district attorney or police officer to
witness an autopsy, it is unusual for them to travel two hours and
cross state lines to do so. The National Association of Medical
Examiners discourages doctors from speaking to law enforcement
officials before conducting exams because because doing so can bias a
doctor's conclusions. At Duncan's trial five years later, one of his
attorneys likened the Oliveaux autopsy to a job evaluation. If it was,
Hayne passed. By that time Hayne was performing the bulk of Ouachita
Parish's criminal autopsies, 30 to 40 per year.
Hayne testified that during an initial examination of Oliveaux's body,
he was able to find bite marks that at the time no other medical
professional had noticed—just as he'd done in the Brewer and Brooks
cases before. And just as it happened in the Brewer and Brooks cases,
Hayne's discovery of potential bite marks gave local authorities
probable cause to obtain a plaster dental mold of the defendant's
teeth, in this case Jimmie Duncan. Hayne then called in West to perform
his unique brand of "analysis." West concluded that the marks were made
by human teeth belonging to the man police and prosecutors suspected of
killing the child.
The Video
Hayne and West videotaped many of their autopsies and forensic
examinations over the years. For whatever reason, the video of West's
examination of Haley Oliveaux was preserved, and Duncan's
post-conviction attorneys found it in the district attorney's file last
year. They were shocked at what they saw. The full video is 24 minutes
long. The brief excerpts that follow show Oliveaux's face on successive
days. At the start of the videotaped examination from December 18,
1993, her right cheek appears free of any noticeable marks. Yet after
the tape cuts to December 19, 1993, the cheek shows prominent signs of
abrasions, which are then exacerbated by West's handiwork.

The full 24-minute video opens with Michael West's initial examination
of Haley Oliveaux's body on the night of December 18, 1993. He notes
several injuries, but at no time does he mention the presence of
possible bite marks on Oliveaux’s right cheek. The video itself shows
no sign of bite marks, scrapes, or abrasions on the cheek.
At the 4:55 mark, there's a cut in the original video, representing the
break between West's initial exam on December 18, and a follow-up
bite-mark analysis on December 19. After the break, West stands over
Oliveaux's body, which now contains a striking red abrasion on her
right cheek—an abrasion that wasn't there before. West then takes the
plaster cast of Jimmie Duncan's teeth and pushes it into the scrape on
Oliveaux's jaw. Over the next few minutes he jams, drags, and scrapes
the dental mold across Oliveaux’s cheek 17 times. For the entire
24-minute video, West uses Duncan's teeth mold on Oliveaux's skin more
than 50 times.
Expert Opinion on the Video
Reason first asked Michael Bowers to comment on the video. Bowers, a
practicing dentist, is a deputy medical examiner for Ventura County,
California and a past chairman of the American Board of Forensic
Odontology’s Exam and Credentialing Committee. He worked with the
Innocence Project to help free Kennedy Brewer.
"This is the best documentation I've ever seen of Dr. West's junk
bite-mark comparisons," Bowers said in a phone interview last month.
When asked how abrasions on Oliveaux's cheek not present when the video
begins could later appear, Bowers answered, "Because Dr. West created
them. It was intentional. He's creating artificial abrasions in that
video, and he's tampering with the evidence. It's criminal, regardless
of what excuse he may come up with about his methods." Bowers added,
"You never jam a plaster cast into a possible bite mark like that. It
distorts the evidence. You take a photograph, or if there are
indentations, you take an impression. But you don't jam plaster teeth
into them." After viewing the video, Bowers submitted an affidavit for
Jimmie Duncan's defense.
Reason also showed the video to David Averill, a dentist and a former
president of the American Board of Forensic Odontology. "The video is
troubling. I don't know how you can explain where those marks come
from. And there's just no justification for him to push the cast into
the skin like that," Averill said. "That isn't an acceptable way to
perform a bite mark analysis."
Duncan's post-conviction attorneys hired San Diego forensic pathologist
Harry Bonnell to review Hayne and West's testimony in the case.
Bonnell, who has been highly critical of Hayne in the past, sits on the
board of trustees for Parents of Murdered Children, Inc., a victim
advocacy group. He has worked for the Armed Forces Institute of
Pathology and formerly served on the ethics committee of the National
Association of Medical Examiners. By email, Bonnell told Reason, "If
what I am seeing on the video is accurate, someone is using the mold of
Duncan's teeth to create an apparent bite mark; this, in my mind, is
criminal tampering with evidence."
In his affidavit for Jimmie Duncan's defense, Bonnell elaborated:
The injury to the cheek of Haley Oliveaux is not seen in hospital
photos...and was generated by using a mold of Duncan’s teeth to create
a bitemark. The injuries on the child’s face are abrasions, which form
almost immediately, unlike bruises, therefore the fact that the marks
are not present in hospital photos and in the beginning of the West
Video makes it medically impossible that Jimmie Duncan could have
inflicted any of these injuries. Nor is it possible that witnesses
could have seen these marks in the emergency room, as abrasions cannot
appear, then disappear, and then reappear at the morgue...stating that
the bites (which they are not) were inflicted within 30 minutes of
death is rubbish, and supported by no scientific fact or literature.
The Tainted Dr. West
West himself never testified at Jimmie Duncan's trial. Between his
examination of Oliveaux in 1993 and Duncan's trial in 1998, the
bite-mark analyst came under fire for his working methods and
credulity-stretching testimony. In 1994, an ethics committee from the
American Academy of Forensic Sciences unanimously recommended that West
be expelled from the organization. West resigned instead. His work was
criticized in such national media outlets as Newsweek, the ABA Journal,
and National Law Journal. By 1998, Duncan's prosecutors recognized the
baggage West carried and dropped him from the case. Still, West
continued to both work with Hayne and testify in Mississippi until well
into the 2000s.
Duncan's prosecutors then turned to Dr. Neal Reisner, a forensic
odontolgist from Scarsdale, New York. Relying only on photos West took
after the examination depicted in the video, Reisner testified that the
marks on Oliveaux's cheek were indeed bite marks, and that "to a
reasonable degree of medical certainty," he could determine that they
came from Jimmie Duncan.
The video was never shown at Jimmie Duncan's trial. It wasn't even
shown to the expert witnesses from either side. Trial Judge Charles
Joiner did view the tape, and inexplicably concluded that it contained
"no exculpatory evidence favorable to the defendant," a conclusion that
the forensics specialists Reason spoke with strongly dispute.
Prosecutors initially refused to turn the video over to Duncan's
attorneys. In one brief filed during pre-trial motions in 1995, they
noted the controversy surrounding West, and argued that "the defense is
somehow hoping to drag Dr. West into this case in order to create
ancillary issues for the jury." A year later, they relented and finally
turned over the tape. For whatever reason, Duncan's trial attorneys
never used the video; they never even showed it to their own expert,
forensic odontologist Richard Souviron. (Duncan's trial attorneys
declined to speak with Reason, because his case is still active.)
Souviron recently had the opportunity to view the video for the first
time. In a new affidavit submitted to Duncan's post-conviction
attorneys, Souviron describes the video as showing "Dr. West, violently
and repeatedly, forcing a mold of Jimmie Duncan's teeth into Ms.
Oliveaux's right cheek. In doing so, Dr. West creates a mark that was
not previously present. Dr. West's behavior and methods are absolutely
not supported by any scientific standards or protocol." Souviron added
in the affidavit that hospital photographs show that "none of the marks
were present when Ms. Oliveaux was at the hospital," and that the
abrasions that Reisner testified about for the prosecution "were
created by the flagrant misconduct of Dr. Michael West."
The Hayne-West Legacy
West was still testifying in Mississippi courtrooms until at least the
year 2000, long after he'd resigned from the American Academy of
Forensic Sciences. As late as 2007, prosecutors were still relying
primarily on West's testimony to keep Kennedy Brewer in prison. And
despite the Brooks and Brewer exonerations, the state has refused to
conduct a review of the hundreds of cases in which West has testified.
Tucker Carrington, director of the Mississippi chapter of the Innocence
Project, argues that West's influence may run even deeper. "You also
have to consider all the cases where someone may have falsely
confessed, or accepted plea bargain for a crime they didn't commit
after being presented with West's findings. Those cases aren't going to
show up in legal searches," he says. "West was also widely used by the
state's social services agencies. His testimony has helped the state
take who knows how many children away from their parents."
The story with Hayne is even grimmer. In August of last year,
Mississippi announced that it finally would no longer include Hayne on
its list of medical examiners cleared to perform criminal autopsies.
The move effectively ended Hayne's reign as Mississippi's de facto
medical examiner.
But as with West, Mississippi officials still refuse to acknowledge
that there was ever a significant problem with Hayne, and have no
intention of investigating just how much damage he may have done to the
state's criminal justice system. Given that Hayne performed
approximately 80 percent to 90 percent of the state's autopsies for
close to 20 years, the number of cases in which he has testified is
likely in the tens of thousands. Worse yet, even in terminating Hayne,
the state agreed to allow him to complete a backlog of approximately
600 autopsies. As of this article's posting, he's still testifying in
Mississippi courts.
