During the 26 years that James Preston spent incarcerated for murder, he always told his family that he didn't commit the crime.
Now, the FBI says their analyst's testimony about key hair evidence in the case exceeded the boundaries of science, raising the possibility that Preston, who died in custody, was wrongfully convicted if not, as his family believes, innocent.
"I sat with him as he passed away and I kissed him and I told him, I said, ‘I'll let everybody know that this is not right, this is not true, and you shouldn't be here,'" his brother, Erick Preston told WFXT-TV in Boston. "That's all they had from the FBI lab, a hair with ‘negroid features'… but he swayed it to make it look like it was my brother's."
The FBI's review of Preston's file is part of a nationwide effort by the Department of Justice and the FBI to re-examine the testimony of FBI forensic experts in serious cases like murder and rape, all done before the advent of DNA testing. More than 2,000 cases involving hair analysis are being reviewed.
