It has all the ingredients for a mystery novel: a missing teenager, a 911 call reporting men with guns and blood found at the scene.
Sheriff's deputies went to a house in an unincorporated part of San Mateo County on a call Tuesday about armed men at a home. They didn't find men with guns but they did find something mysterious.
Instead, they discovered blood and found out a teenager who was supposed to be at the house is missing.
Someone called 911 at about 9:15 p.m. and said two armed men were at the house in the 2800 block of Westmoreland Avenue in unincorporated Redwood City's North Fair Oaks neighborhood, according to sheriff's Lt. Ray Lunny.
When deputies got to the house, they learned 17-year-old Luis Antonio Ortiz had been babysitting his two younger brothers when he disappeared. The deputies found blood in the yard and on some of Ortiz's personal property, Lunny said.
Family and friends of Ortiz said he is not involved in any gangs or other high-risk lifestyles, according to Lunny. Ortiz is now officially listed as a missing person and police are pounding the pavement looking for him.
Ortiz is about 5 feet 6 inches tall, weighs 145 pounds, and has brown eyes, brown hair and an olive complexion.
Anyone who has information about Ortiz's whereabouts is asked to call the 24-hour San Mateo County communications line at 650-363-4911.
