This time it was Gerard Richardson. As The Verge outlined in September, Richardson was convicted of murdering a New Jersey woman in 1994 after a forensic odontologist concluded that the shape of Richardson’s jaw and the orientation of his teeth matched a bite mark on the murdered woman’s back. Their goal: to determine whether saliva swabbed from the bite mark in 1994 matched Richardson’s genetic makeup. Given this new information, prosecutors dropped Richardson’s case, and a judge declared him exonerated.
