On a Sunday morning in March 2016, Ronald F. Heist, 71, was killed while working at the Fort Littleton interchange of the Pennsylvania Turnpike. A retired York City police officer, Heist was employed as a security guard for a contracted detective agency and was at the toll plaza when the attack began around 7 a.m.

Briggs, attempted an armed robbery. Briggs first confronted two tollbooth employees and tried to tie them up; they fought free. When a fare collection vehicle arrived and toll collector Danny Crouse, 55, approached, Heist exited the passenger side and Briggs opened fire, fatally wounding both Heist and Crouse. Briggs then fired at the armored vehicle, drove it briefly, and began transferring money before state troopers confronted him. An exchange of gunfire left Briggs shot and killed at the scene. Investigators reported Briggs had filed for bankruptcy the previous year with more than $300,000 in debt.

Does anyone have memories of the Fort Littleton interchange that morning or information that wasn’t public then?
