Karissa Alline Schell, 16, disappeared from Turlock, California after leaving a friend’s house between 2:00 and 3:00 a.m. on April 21, 2011. She told the friend she would return later that morning but never came back. At the time she was 5 feet 6 inches, about 140 pounds, with brown hair dyed burgundy, distinctive piercings on her septum, navel, ears and cheek, and a tattoo of lips on her neck. She was wearing dark-colored jeans, a black sweatshirt and a black and gray shirt with a peace sign when last seen.

Authorities initially treated the case as a runaway, but Karissa had no prior history of running and her family says there was no reason for her to leave. Her phone was later linked to Redwood City, prompting consideration of trafficking as a possible lead. The case is classified as endangered missing and age-progressed photos have been released. If anyone has information about Karissa’s disappearance, contact the Turlock Police Department.
