Quiroz is being held without bail in Sonoma County Jail on suspicion of being an accessory to murder, according to the sheriff’s office.

The suspects are believed to be responsible for the shooting death of 15-year-old Nathaniel Torres at a birthday party on Windsor Avenue at 12:47 a.m. on June 22.

Three other victims—ages 17, 21 and 24 — were also shot but survived their injuries.

Witnesses told investigators the shooter fled in a blue Nissan compact car with three other people. Deputies initially said that a female was believed to be driving the car, but they have identified no female suspects.

Deputies said the shooting is believed to be gang-related and the sheriff’s office considers the suspects armed and dangerous.

Anyone with information about Caballero, Morgan or Aguilar has been asked to call the Sonoma County Sheriff’s Office investigations bureau at (707) 565-2185.

Anyone who sees the suspects has been advised to not approach them but instead call 911 immediately.
