The murder rate in Philadelphia is still going up. And its kids doing the killing.

The first incident occurred about 4 p.m., when a 23-year-old man was found severely wounded in East Germantown. The fourth in the cluster happened shortly after 6 p.m., when a gunfight broke out among spectators attending a youth basketball game at a recreation center in North Philadelphia near Brewerytown.

When that exchange was over, a 17-year-old boy was left dying of multiple shots to the torso; a wounded 18-year-old man and an automatic weapon were found inside a bathroom at the rec center; and police had arrested one of the alleged shooters.
