On Father’s Day in Lancaster, Pennsylvania, 44-year-old Anthony Marshall was killed after trying to intervene in a fight at a party on Lafayette Street. In the early morning hours of June 16, 2019, Marshall and his 25-year-old son, Tyquane Christian, left the gathering after a dispute involving another man and Shawn Nasim Connelly. The group crossed paths again; after a verbal exchange Connelly allegedly pulled a handgun and fired multiple shots. Marshall was struck in the torso and later died at a local hospital. His son was wounded in the arm and survived.

Investigators identified Connelly as the shooter using witness interviews and surveillance footage that reportedly showed him drawing a gun and firing before fleeing with three other men. The firearm was never recovered. Connelly was charged in September 2019; a jury later convicted him and he received life without parole plus additional years.
