BUTLER — More than 100 state troopers have lost their lives on the job since the organization’s founding in 1905, and 10 of those served Troop D.

Their lives were commemorated at a State Police Memorial Day ceremony at the Butler barracks on Tuesday, May 2.

The day was one of recognition of the families those troopers left behind, and of the hard work done by current officers, according to Trooper Josh Black, public information officer.

“It’s a celebration of the families who’s relatives gave the ultimate sacrifice, and a celebration of each other, as we come together to share stories with current and retired members,” he said.

Black said that Pennsylvania was the first to start a state police force.
