A teenager was fatally shot by a neighbor who became enraged after he was hit by a snowball, police said.

Teven Rutledge was having a snowball fight with a friend on Sunday, his 16th birthday, in the city's Feltonville neighborhood. They hit a neighbor, who came back with a gun and shot the boy in the head, according to police.

Rutledge was taken to Temple University Hospital, where he was pronounced dead around 11:30 a.m. Monday, according to police.

It was unclear if Rutledge meant to hit the man. After the neighbor was hit with the snowball, police said, he exchanged words with the teen before going home and getting the gun. He then returned and shot the boy before fleeing.

"It's horrendous to shoot somebody over a snowball," Chief Inspector Keith Sadler said at a news conference.

Investigators on Monday were still looking for the neighbor, whose name was not released.
