peer-reviewed, published studies establishing the scientific bases and
reliability of many forensic methods. Moreover, many forensic
labs are underfunded, understaffed, and have no effective oversight.

the Illinois lab released false figures and fired two lab employees in
retaliation for criticizing an ethically questionable contract. Sheppo knows how

commander of the Douglas County (Omaha) crime scene investigations
unit is facing federal and state charges over accusations that he

Nebraska couple's murder. He was just making the evidence fit the
coerced confession. Evidence tampering.
UPDATE: 3/23/10 - A
judge on Tuesday, March 23, 2010 convicted a top crime scene
investigator of evidence tampering, after prosecutors argued that the
investigator planted blood from a slaying victim in a car linked to two
innocent suspects to bolster the case against them. Cass
County District Judge Randall Rehmeier said he didn't
believe Douglas County CSI director David Kofoed's excuse that the
victim's blood ended up in the car because of a sloppy mistake.
Rehmeier said there was enough evidence to show that Kofoed
intentionally planted fake evidence. Guilty.
UPDATE: 3/25/10 - CSI director David Kofoed had a
reputation as a man who could find things others couldn't. That
reputation was destroyed when the Douglas County
CSI director was convicted of planting blood evidence during a murder
investigation. The conviction throws into doubt the legitimacy of other
cases on which he worked, and some of those he helped put behind bars
are likely lining up to appeal. Flood of appeals expected.
UPDATE: 6/2/10 - Former CSI director David Kofoed was sentenced
to between 20 months and 4 years in prison for tampering with
evidence. He plans to appeal.

Wisconsin. In 1985, when
Robert Lee Stinson of Milwaukee was 21 years old, he was convicted of
the murder of a 63-year-old woman who had been savagely beaten to death
the previous year. Robert's conviction was based on bite mark
evidence that didn't even match--he had a tooth missing where the bite
marks indicated a tooth, a fact that didn't bother the state's
"experts" at all. DNA evidence rules him out conclusively. Junk bite mark evidence

Jerome Buting has filed a complaint about some of the big errors that
have been uncovered at the Wisconsin Crime Lab. For
example, an employee at the Milwaukee bureau of the crime
lab made up results. He "falsified the data" in a case by saying a
finger print didn't match anyone in a database before he knew whether
it did or not. In
March of 2006, an employee at the Madison bureau of the lab was
suspended for being "intoxicated" on the job. That

driving under the influence of methamphetamine and causing Hudnall to
crash. Defense attorneys have learned that testing of the
defendant's blood was conducted by a lab analyst who is a close friend
of the dead deputy's family. Cops in lab coats.
But wait -- there's more. When Daniel Willsey's defense attorneys
went back to court to argue motions related to mishandling evidence by
the DA office's crime lab, everyone got a big surprise. The crime
lab had "inadvertently" destroyed the sample of Willsey's blood that
the lab claimed tested positive for methamphetamines. Gosh, it's
not like the DA wanted to make sure Willsey's defense attorneys can't
have a private lab test the sample. Ooops -- Butterfingers.

Mississippi: The Innocence

Medical Examiner, and to stop using state pathologist Dr. Steven

convictions of Kennedy
Brewer and Levon Brooks. His credentials and
the results of his work have been solidly discredited for
several years, but he is under no oversight because the State Medical
Examiner position has been vacant for more than a decade. How many more
wrongful convictions before the state acts responsibly?
But Dr. Steven Hayne is only half of the despicable duo. Forensic
odontologist Dr. Michael West found "bite marks" no one else could see
on the bodies of the little victims in both cases, and in both cases,
testified that Kennedy Brewer and Levon Brooks were each guilty. "If
you fabricate evidence in a capital murder case, where you
know that if the person's convicted they are going to be executed
as far as I'm concerned that's the crime of attempted murder,''

Brewer of Macon, Mississippi, a mildly retarded, Black

awaiting retrial. Because you can bet, the local authorities plan

can't look for a DNA match because Mississippi doesn't have a DNA
database -- which is news to the state's crime lab director. The
prosecutor will bring back his star witness, dentist Dr. Michael West,
whose bite mark testimony has been disproven by DNA in other cases, and
who resigned from professional forensic dentistry groups to avoid

Justice Goes to
the Dogs. On
a warm August night in 2004, Michael Espalin and his dog
watched Riverside, CA firefighters douse seven burning palm trees on a
residential street. It was 1 a.m., an unusual time to be walking a dog,
or so thought an arson investigator. After
answering a number of questions, Espalin, then 31, was asked to rub his
face and hands on a gauze pad and sent on his way.
Half a year later, Espalin was charged as a serial arsonist,
accused of lighting 21 fires, mostly trees and bushes, in
eyewitnesses or traditional evidence linked Espalin to the
crimes. But the Riverside County district attorney's office built a
case against him based on a bloodhound allegedly picking up his scent
on a charred incendiary device and cold crime scenes and matching it to
the pad. After
Espalin spent two years in jail awaiting trial, a jury
deadlocked 9 to 3 in January for acquittal. Most jurors did not believe
that the bloodhound, Dakota, found Espalin's scent at the scene of the
fires days and weeks after they were set. Prosecutors
say they intend to try Espalin a second time.
Fall Apart. Defense
attorneys for James A. Kulbicki offered a string of
alibi witnesses, and he flat-out said he didn't do it. He was, after
all, a Baltimore, MD police sergeant, and, he insisted, not a
killer. But a
state police ballistics expert named Joseph Kopera helped
convict the officer by saying that bullet fragments found in his truck
and in his mistress' head could have come from his gun - testimony that
is now being questioned. Kopera
recently killed himself after being confronted with evidence that he
lied about his credentials. Kublicki's attorneys
challenged Kopera's findings and assertions in
court papers filed a year earlier, arguing that the firearms examiner's
testimony did not match his notes. And that was before they discovered
that Kopera claimed to have degrees that he never earned.
It's easy to understand why the Baltimore DA wanted to blindside James
Kulbicki and his attorneys. They have to be steaming mad after
Kulbicki's lawyers exposed the systematic forensic fraud committed by
police ballistics expert Joseph Kopera. But their reach exceeded
grasp when they did DNA tests -- without court approval or notice to
Kulbicki's lawyers -- on bone fragments that were contaminated 14 years

Ohio were convicted of the 1997 beating murder of 74-year-old Alice
Zolkowski, based in large part on the testimony of a third man arrested
in the same incident. Police crime lab analyst Joseph Serowik
testified the informant had only one drop of blood on his shirt,
supporting the man's claim that he was an observer, not a participant
in the crime. A lab audit found seven
blood stains on the informant's shirt.
Serowik either lied about or failed to conduct thorough blood
tests on the clothing of an eyewitness who said Siller and Zimmer had
beaten the woman into a coma. Serowik's testimony amounted to perjury

Evidence for Shaken Baby Syndrome
theory of shaken baby syndrome rests on core assumptions: shaking is
intentional and violent; the injury an infant receives from shaking is
severe; and subdural andretinal bleeding is the result of criminal
unless proved otherwise. Retinal haemorrhage is one of the
used, and many doctors consider retinal haemorrhage with specific
pathognomonic of shaking. However, in the March 27, 2004 issue of the
Medical Journal, Patrick Lantz et al examine that premise and
that it "cannot be supported by objective scientific evidence."
