It's easy for a missing person's case to fade from the headlines -- once they're added to the stack of cases growing cold, they're replaced by new stories. But for the families and friends of those who've disappeared, the story repeats itself each day they're not found.
We decided to bring some of those faces back into the news; here are six people went missing in San Francisco in the last six months -- and who have yet to be found.
If you have any information on these disappearances, or believe you have seen them, please contact the SFPD at 553-0123, the anonymous tip line at 575-4444, or text a tip to TIP411 with "SFPD" at the beginning of the message.
