SAN LORENZO — A San Lorenzo teenager who disappeared almost three weeks ago is still missing.

Jann Derrick Lactawen, 19, was last seen Oct. 22 around 11 a.m. at his home in San Lorenzo, according to the Alameda County Sheriff’s Office.

The 5-foot-7 teen is Filipino with brown eyes and black hair, and weighs around 110 pounds.

According to a flyer posted by his family, he was last seen in a white T-shirt, black basketball shorts and a black hat, and his Clipper card reportedly indicates that he exited at the Montgomery Street BART station that afternoon around 3:15 p.m.

His family has launched a GoFundMe campaign to pay for a private investigator. The family said Lactawen told his parents that morning that he was going to San Francisco to “chill.” His family said he did not pack any belongings.

Anyone with information about Lactawen’s whereabouts is asked to contact the sheriff’s office at (510) 667-7721.
