Human Skull Found Near Los Gatos Human Skull Found South of San Francisco The skull was found by a hiker outside Los Gatos in an unincorporated area of Santa Clara County. Right now, LE doesn't know the age, race, sex or how long it's been there. They also said they aren't ruling out the possibility that it belongs to an ancient Native American. There's some speculation that it's Sierra Lamar, who was abducted while walking to her school bus stop in Morgan Hill in March 2012. A man was arrested and charged with her murder only a couple months later, but Sierra's body has never been found. Los Gatos is about a 30 min drive from Morgan Hill. There's 32 people listed on NamUs who are missing from Santa Clara County alone. And a lot more who are missing from neighboring counties. So the skull could really belong to anyone right now.
