NOVATO, CA -- The Marin County Sheriff's Office on Nov. 22 announced a new arrest in the murder of a Novato High School student in May and the attempted murder of another student.

Edenilson Misael Alfaro, 22, was arrested in Maryland on Nov. 9, according to the sheriff's office.

Edwin Josue Ramirez Guerra, 17, was killed and another then-17-year-old was stabbed and shot in the head and chest but survived the attack on a public trail at the end of Fairway Drive in Novato.

Sheriff's deputies previously arrested two Novato High School students, Juan Carlos Martinez Henriquez, 18, and Edwin Oswaldo Guevara, 17, on suspicion of the murder and attempted murder.

Javier Guevara, 19, of San Mateo, also was named a suspect but remains at large. Elmer Fernando Machado-Rivera, 21, of San Rafael, pleaded guilty to being an accessory after the fact.

Sheriff's officials said seven people were believed to be involved in the murder and attempted murder.
