Suspect in Fatal Shooting of Pennsylvania State Trooper Shot Dead, Police Say

— -- The suspect sought in connection with the fatal shooting of a Pennsylvania state trooper was shot dead by police Saturday morning after an hours-long manhunt, authorities said.

Pennsylvania State Police had been searching for 32-year-old Jason Robison in connection with the shooting of Trooper Landon Weaver on Friday night. Police said after Weaver's killing that Robison should be considered "armed and dangerous" and that it was believed he had dyed his hair purple.

The state police said in a statement today that troopers searching the area encountered Robison at an unoccupied mobile home not far from his residence at about 9:50 a.m. local time.

"When confronted by the troopers, the armed suspect failed to obey commands and made an overt threat toward the troopers," the police statement said. "Troopers were forced to discharge their weapons resulting in the suspect being fatally wounded."

The slain trooper, Weaver, was killed while investigating a protection-from-abuse violation at a residence in Juniata Township in Huntingdon County on Friday around 6:30 p.m. local time, according to the police statement. Weaver was interviewing Robison inside the home when Robison "gained access to a firearm" and fatally shot the trooper, according to the statement.

Soon after the shooting, authorities launched a manhunt for Robison and a remote Huntingdon County area was closed off in the search.

Weaver joined the Pennsylvania State Police in December 2015, the agency said. Gov. Tom Wolf said the fallen trooper will be remembered for his bravery and willingness to serve.

"Landon will always be remembered for his bravery, his sacrifice, and his willingness to serve," Wolf said in a statement Friday night. "The state police are our best and bravest Pennsylvanians, who risk their lives to keep all of our families safe."
