Kennedy Brewer was sentenced to death in Mississippi of the 1991 murder of a 3-year-old girl. His conviction was based largely on the testimony of Dr. Michael West, forensic dentist who claimed that multiple abrasions on the child's partially decomposed body matched the upper bite of Brewer. The incorrect matching of bitemarks has been a cause of at least four wrongful convictions later overturned by DNA evidence, and West’s unorthodox methods have been debunked by many experts and he has been expelled from several professional associations.
DNA testing in 2002 excluded Kennedy Brewer as the source of the semen recovered from the child. Even though the court threw out the conviction and death sentence based on the new DNA evidence, the local prosecutor announced he would re-try Mr. Brewer and use Michael West again as a bite mark expert. The Innocence Project is co-counsel, along with Brewer's local counsel for the retrial.
In a Fox News article yesterday, Radley Balko writes about West’s questionable past and the unreliable nature of bitemark evidence.
Even in an already imprecise field, Dr. West has taken forensic odontology to bizarre, megalomaniacal depths. West claims to have invented a system he modestly calls "The West Phenomenon," in which he dons a pair of yellow goggles and, with the aid of a blue laser, says he can identify bite marks, scratches, and other marks on a corpse that no one else can see — not even other forensics experts.
Conveniently, he claims his unique method can't be photographed or reproduced, which he says makes his opinions unimpeachable by other experts.
