In Philadelphia, a Black man who spent nearly three decades behind bars for a crime he says he did not commit was released from prison Friday, after District Attorney Larry Krasner’s office said he had not received a fair trial. Eric Riddick was convicted of murdering his childhood friend in 1992 and sentenced to life in prison based on the testimony of a single eyewitness, who recanted the testimony in a 1999 affidavit. An investigation by a firearms expert in 2012 ruled out the possibility that Riddick could have been the shooter. Riddick won his release after agreeing to plead guilty to a lesser third-degree murder charge.
