The other trooper killed – Branden T. Sisca, 29 – was from Montgomery County.
Mack’s remains were returned to Bristol Borough Monday afternoon in a precession of police vehicles that came off I-95 and traveled under two fire department ladder trucks with an American flag hanging under along Mill Street.

Mack and Sisca were out on I-95 southbound near the stadium complex in Philadelphia just before 1 a.m. when they were struck by a vehicle. The two troopers were on the highway for a report of a person walking on I-95.
At the time of the crash, they were helping the male pedestrian into a state police SUV, according to authorities.
