Authorities said Trooper Landon Weaver was shot and killed by Robison at about 6:30 p.m. Friday when the officer investigated a “domestic-related incident” at a home on Bakers Hollow Road in Juniata Township in Huntingdon County. The area where the shooting occurred has been closed off while police officers search for Robison, the report said.
Robison made his feelings toward law enforcement known on his Facebook page less than two weeks before the killing.
Robison, according to court documents, has previously been arrested about a dozen times with charges ranging from simple assault to arson.
Weaver enlisted with state police in December 2015 and was assigned to Troop G, Huntingdon. He is the 97th member of the Pennsylvania State Police to be killed in the line of duty, according to authorities.
