WILMINGTON (CBSLA.com) — A 17-year-old boy who had just come home from a day at the beach was shot and killed early Tuesday, just two days before he was set to graduate from high school.

The shooting was reported at 12:30 a.m. in the 900 block of I Street, Los Angeles police Sgt. Bradley Hearn said. The boy’s mother, who had been waiting for her son to come home, was awakened by the shots and ran out toward the sound.

The boy, later identified as Fabian Nunez, was taken to a hospital, where he died.

Family members said he was supposed to graduate from Narbonne High School on Thursday, and that he had been very excited to receive his diploma. A Facebook page believed to belong to Fabian included pictures of him in a White Sox ballcap and holding a fish he had caught, a meme that said “My biggest goal is to graduate. And prove everyone who doubted me wrong.”; and a picture of a school letter that said he was on track to receive his diploma.

Los Angeles police Detective David Cortez says there is no suspect or vehicle information available.

“But someone has said there was a suspicious car that was cruising around in the neighborhood. The four juveniles were hanging out when someone parked in the alley straight across from where they were standing,” he said. “Someone dressed in all black ran up and started firing shots at them.”

None of the other boys were hurt.

The shooting is believed to be gang related, but detectives say there is no indication that the boy was involved in a gang.

A student at Narbonne High School said that Fabian had been bullied by gang members at the school, but it’s not clear if it led to the shooting.
