Police say a 23-year-old suspect has turned himself in after a shooting that injured 11 people at a Philadelphia cookout.

Authorities say Dominic Lamar was taken into custody Monday. He faces charges of attempted murder and other offenses in the June 20 shooting.

Investigators are still searching for a second 23-year-old suspect.

Witnesses told police that the men fired a shotgun down a west Philadelphia block during a cookout. Police say the victims were wounded by birdshot from the shotgun blasts.

The victims included a 1-year-old girl, an 11-year-old boy and a 12-year-old boy.

It's unclear if Lamar has an attorney who could comment on the charges.
