At about 12:30 p.m. Timothy Schlafer, who has the maturity level of a 10- to 12-year-old, walked away from Civic Park, located at 1375 Civic Drive, police said.
A supervisor for the youth camp called police around 1:50 p.m. and reported that the boy had wandered from programs before but has a disorder that leads him to look for food instead of a way home.
The boy had no money or cell phone and police said he would likely beg for food or BART tickets.
At about 1:25 p.m. he was spotted begging for bus transfers at the Lafayette BART station. A police dog was able to confirm that Schlafer had been on the San Francisco-bound platform.
Schlafer was then located at about 7:30 p.m. at a BART station in San Francisco and taken back to his parents, police said.
