A 22-year-old college student killed by Pennsylvania police responding to a possible burglary had just realized he was at the wrong home and was waiting for friends to come get him when he was shot, his father said Wednesday.

A college student was fatally shot by a police officer after apparently ringing the doorbell of a residence he thought was his friend's house, his parents said.

Glenn Pysher was trying to find his friends when he accidentally knocked on the door of the wrong house. The homeowners called 911 to report an attempted break-in.
