The Crime
On August 13, 1987, the victim was found dead in her home. She had been raped and suffocated with pills that had been forced down her throat. Police were initially looking for a stranger that was seen walking through back yards in the area that day. However, the police focused on 24-year-old Barry Laughman, a neighbor whose pinkie finger couldn’t bend properly. Police suspected that this injury could have been sustained during the commission of the crime.
The Confession
Laughman had an IQ of 70 and was said to be functioning at the level of a 10-year-old. Several weeks after the crime, police told Laughman that his fingerprints were found at the scene. He then confessed to the police. There were numerous discrepancies between the crime scene and his confession, such as his explanation of his point of entry conflicting with a seemingly undisturbed window at the scene. He also stated that he had killed the victim on August 12, but a neighbor reported seeing her in her yard on the morning of August 13.
The Biological Evidence
The Pennsylvania State Police conducted serology testing on semen found on the victim’s vaginal swabs and found evidence of Type A blood, either from the victim or the perpetrator. The victim was a type A secretor and Laughman is a type B secretor. The police chemist testified correctly at trial that the victim’s profile could have masked Laughman’s profile. The analyst testified incorrectly, however, that bacterial degradation could have changed type A blood to type B or vice versa.
Post-conviction
PCR/DQ Alpha DNA testing was attempted in 1993 by Cellmark Diagnostics on the vaginal swabs collected from the victim but results were inconclusive. David J. Foster, of Costopoulos, Foster & Fields, represented Laughman. By 2003, the samples were thought to have been lost, but were then discovered to be in the possession of a former Penn State professor residing in Germany. In November 2003, Orchid Cellmark performed Y-STR DNA testing and reported that Laughman had been excluded. He was released from prison under supervised house arrest, but the district attorney still planned to press charges. On August 26, 2004, however, Adams County District Attorney Shawn C. Wagner dropped all charges against Laughman.
