SAN JOSE, Calif. (KRON) — A San Jose man was booked into jail over the weekend after he flagged down a police officer to tell them that he had killed two people, according to authorities.

Marcelino Castro, 28, approached a San Jose Police Department officer at 5:14 p.m. Saturday and said he committed a homicide, police said.

“Officers responded to the area of Lelong (Street) and Alma Avenue where they located a deceased male victim,” SJPD wrote.

Castro then provided more information about a second homicide, according to police. Detectives went to the area of Autumn Parkway and Coleman Avenue, where they located another body.

Castro was arrested on two counts of suspicion of murder.

Investigators do not believe the homicides occurred on the same day that Castro flagged down officers, police said at a news conference Tuesday

Investigators are working to determine the motive and circumstances surrounding the killings.
