Police are not commenting on whether the shooting was gang-related, but Towne Gardens Plaza is next door to the Towne Gardens housing complex that federal prosecutors believe served as a base of operations for the CBL/BFL street gang.

The FBI arrested 11 alleged gang members last August and charged one of them with two murders.

"We don't know that for a fact," Rinaldo said of possible gang involvement Sunday. "At this point, we're still in the very early stages of our investigation."

Rinaldo said police are still trying to determine if there was more than one shooter, but declined to comment on whether there are any known suspects.

A man who lives a block away from the shooting said he heard at least a dozen gunshots while watching TV Saturday night.

Once he came outside, police and paramedics were already on the scene at Town Garden Plaza and across the street outside a two-story building on William, he said.

The man, who spoke on the condition he not be named, said he saw stretchers at both locations.

A red teddy bear sat outside an entrance to the William Street building.
