The family of Moses Walker Jr., the Philadelphia police officer killed in an attempted stickup in August, filed a federal lawsuit Tuesday against the Pennsylvania Board of Probation and Parole, saying state officials caused Walker's death by allowing his alleged killer to roam the streets when he should have been behind bars.
"Officer Walker's murder occurred as the result of a systemic breakdown," said Michael F. Barrett, one of the attorneys representing Walker's family, at a news conference at his Center City office. "Officer Walker would not have lost his life if the chairman of the Pennsylvania Board of Probation and Parole and his subordinates had done their jobs."
