Both victims were transported to a local hospital, where the 15 year-old died from his wounds. The 16-year-old was treated for a gunshot wound to the leg and remained hospitalized in stable condition.
"I heard the gunshots. I was sitting inside watching TV and when I came outside all I saw was the guy lying on the grass. I didn't see who did it or nothing," said Jack Garror.
Garror said his granddaughter had gone inside just seconds earlier when the shooting started. There is a bullet hole on the front wall of his home.
Investigators said the shooting appeared to be gang related, but they do not believe the victims had any gang connections.
Homicide detectives from the Foothill Station were assigned to investigate the case. Davis said the suspect's vehicle was black, but no other details were released.
There have been a number of homicides in the area over the last few years. Residents said there are several gangs and they often hear gun shots.
"The crime has definitely increased. It can be a little bit scary, you never know what's going to happen," said resident Brent Seymour.
Anyone with information on the shooting was urged to call the LAPD's Foothill Station at (818) 756-8861.
