HARRISBURG, Pa. (AP) — Prosecutors and corrections officers are urging a review of Pennsylvania’s parole practices following the arrests of three parolees in unrelated homicides over the past two months. One is a convicted murderer who got out of prison in March and is charged with killing an 8-year-old boy two weeks ago. Two other parolees released from prison in the last two years are facing charges in the beating death of a 2-year-old Baltimore boy and the strangulation of a Hershey, Pennsylvania, woman.
