Friends and the San Mateo County Sheriff's Office are seeking help in locating Keith Green, 27, of Millbrae, who was last seen in Millbrae shortly after 10pm on April 28th, but whose cell phone was discovered in Golden Gate Park shortly after his disappearance.
[Update, 5/18: The San Mateo County sheriff's office has announced that Green was killed in a homicide, and his body recovered near Sonoma County's Geyserville last week.]
Green's friends have launched a Facebook missing persons page with details about the shoes he was wearing at the time of his disappearance, and missing person flyers have gone up around the city, including the one above, at Haight and Clayton.
Below is an enlarged image of Green from the Facebook page:
According to NBC Bay Area, the sheriff is considering the disappearance suspicious; the morning after he was last seen, Green's cell phone was found by a hiker in Golden Gate Park, NBC reported. He left home without his car and wallet.
Update 5/22: Multiple outlets are reporting that Green's ex-girlfriend Tiffany Li and her current boyfriend Kaveh Bayap were arrested Saturday night in connection with Green's murder. Li and Bayap were arrested in Hillsborough and booked on suspicion of murder and conspiracy. A third person may have been arrested as well, according to the San Jose Mercury News, though police have not yet commented on that person's identity or connection to the case.
Li was the mother of at least one of Green's two children. On the day he vanished, Green was reportedly "going to meet an ex-girlfriend to work out a custody problem," a family friend told ABC 7.
