A man wearing a New Jersey Devils cap stabbed another man to death in a posh section of Philadelphia after an argument about the hat turned physical, police said.

The stabbing happened just after 3 a.m. Sunday in the city's tony Rittenhouse Square, officials said. Emergency responders found 24-year-old Colin McGovern, of Churchville, lying on the sidewalk with multiple stabs wounds to the torso. He was pronounced dead at a hospital.

A preliminary investigation showed McGovern and a friend were arguing with 40-year-old Steven Simminger over Simminger's Devils cap and the argument escalated into a physical altercation, according to authorities.

Simminger, of Media, is charged with murder and related offenses.

No attorney information is listed for Simminger in online court documents.
