It was about 7:15 p.m. Friday when police say an unknown car drove by a group of kids, and someone inside the vehicle fired several shots, killing Steven Guzman.
As the memorial for the shooting victim grows, so does the number of police officers driving through the neighborhood.
"They've been patrolling, pulling people over, asking questions, people have been cooperating though, so trying to find out who it was did this," said Lydia Ponce of San Bernardino.
Ponce said she's relieved to see the increase in patrols. While she says she still feels safe, the shooting remains on the minds of many residents.
"Senseless, there's no reason for a little kid like that to be shot down like that at all, for no reason, no matter what they did or didn't do, you know," Ponce said.
"If they want to get at a person, at least get in a fight or something, but not to go and take their lives away," said Yvonne Almarez of San Bernardino.
Some residents speculate that the attack might have been retaliatory action between two rival tagging crews. Police aren't ruling that out, but right now, they say they just need more information.
"This is a tragedy that occurred to a family, but it's also a tragedy that occurred to a neighborhood, and any information that we can obtain from the public, we're seeking out," said Lt. Paul Williams of the San Bernardino Police Department.
Anyone with information is urged to call the San Bernardino Police Department at (909) 384-5742.
