A man who authorities believe shot and killed a Pennsylvania State Police trooper on Friday has died, authorities said.

State police announced Jason Robison’s death in a Facebook post on Saturday morning, but did not release any details.

The New York Daily News reported that Robison was killed about 10:30 a.m. “during an encounter with police” at his mobile home in Huntington County, but troopers have not confirmed that report.

Robison had been the subject of a growing manhunt since police believe he shot Trooper Landon Weaver around 6:30 p.m. Friday. Weaver was responding to a domestic violence call on Bakers Hollow Road in Juniata Township, about 85 miles east of Pittsburgh.

Weaver is the 97th member of the Pennsylvania State Police killed in the line of duty.
