According to Kristen De Groot of the Associated Press, Steven Simminger is in custody after an argument about the Devils hat he was wearing got physical around 3 a.m. Sunday.
Simminger, 40, allegedly stabbed 24-year-old Colin McGovern in the torso, and McGovern died as a result of his injuries. McGovern had been in Philadelphia with three friends when they came across Simminger. The pair allegedly got into a fight after McGovern made a comment about the cap.
"This was over a hockey cap," Homicide Capt. James Clark said.
Simminger was treated at a Veterans Affairs hospital for minor injuries.
