Santa Rosa Police have arrested a 13-year-old boy for suspicion of attempted murder in connection with a June 9 shooting at Martin Luther King Park in south Santa Rosa.

Gang crimes investigators had his house under surveillance when he left home Wednesday with his mother, police said.

He was interviewed, then booked into Sonoma County Juvenile Hall on two counts of suspected attempted murder, as well as shooting at an inhabited dwelling or car and multiple gang enhancements, police said.

The boy is an active gang member who was arrested about three weeks ago by property crimes detectives investigating a rash of gang-related graffiti in Bennett Valley and later came under scrutiny in connection with the shooting, authorities said.

The victims in the case, a 12- and a 14-year-old boy, said they were at the park the evening of June 9 when a teen on a bike approached and the trio flashed gang-related signs and shouted epithets at each other, police said.

The youth on the bike then pulled a handgun from his clothing and fired several shots at the other two as they ran away, police said.

Neither was hit, and no one was injured, though the park was filled with people playing soccer and otherwise enjoying a summer evening.

One bullet lodged in a car parked on Temple Street, police said.

The suspect fled the area on his bike and was not found that evening, but was later identified as the youth arrested Wednesday, police said.

A warrant to search his house was obtained before he was put under surveillance Wednesday, police said.

Anyone with information about the shooting is asked to call Detective Brian Sinigiani at (707) 543-3670.
