DONORA, Pa. (AP) - A part-time police officer has been charged with stealing $1,300 worth of heroin from the evidence room at a southwestern Pennsylvania police department.

Twenty-nine-year-old James Johnson V, of Monongahela, didn't immediately return a call for comment after Washington County District Attorney Eugene Vittone announced the charges Wednesday.Vittone says Donora police seized two batches of heroin during the search of a home in August, one containing 237 individual dose bags of heroin and the other 133 bags. The drugs were stored in separate, sealed envelopes and by the time an officer went to send them to a crime lab for testing two days later, the 133-bag envelope was missing.Investigators used surveillance video to determine Johnson entered the room, and say he acknowledged stealing the drugs for personal use.Court records don't list a defense attorney.
