A 20-year-old man was arrested Sunday in connection with a fatal shooting in Novato last week, according to a tweet from the Marin County Sheriff's Office.
Elmer Fernando Machado-Rivera, of San Rafael, was arrested on suspicion of conspiracy after the fact in the homicide case stemming from the shooting death of Novato High School student Edwin Josue Ramirez Guerra, 17, of San Rafael. Another student also was shot and stabbed in the incident but survived.
Law enforcement agencies conducted two raids at two homes in the Novato area on Thursday and arrested two suspects, both minors, who reportedly were classmates of the victim. In the hunt for a third suspect, another home was searched Saturday, but no details were provided.
Sheriff's officials did not provide any further information about Sunday's arrest, except to say that detectives are still in pursuit of a third suspect in the shooting.
Novato High School canceled classes the day after the shooting and had a scheduled closure Friday. It will resume classes on Tuesday.
