The gunman was fatally shot by police, Pennsylvania State Police Commissioner Col. Christopher L. Paris said. Law enforcement officials said officers were attempting to arrest the suspect after charges of stalking and criminal trespass were filed earlier in the day. Paris said the two wounded officers were in "critical but stable condition" at WellSpan York Hospital, which implemented enhanced security protocols in the immediate aftermath. The tragedy comes amid a series of violent attacks targeting Pennsylvania law enforcement this year.
