Seifuddin Collier, 24, was shot once in the abdomen and died after surgery following an incident in Upper Darby, Pennsylvania, on the evening of January 15, 2018. Authorities described the shooting as arising from a complicated, ongoing domestic dispute. Reports say Collier confronted another man who was with a woman in a car; after a verbal exchange, Collier reportedly armed himself and the other man, a licensed concealed carry permit holder, drew his firearm and shot Collier.

The shooter reportedly drove home, called 911, placed his weapon in the street per dispatcher instructions and waited for police. Upper Darby Police Superintendent Michael Chitwood characterized the event as stemming from a continuing dispute, but the shooter’s name was not released publicly.
