Details of Disappearance

Sidi was last seen in San Francisco, California on May 21, 2013. He went to visit a former high school teacher in the 100 block of Oak Street at 11:40 a.m. He spoke to his father on his cellular phone at 1:30 p.m. and said he was taking the bus to the park. His phone went dead at 2:00 p.m. and Sidi has never been heard from again. His phone last pinged on the eastern end of Golden Gate Park.

He rarely left the house for extended time periods and usually kept his family informed as to his whereabouts. An extensive search of the area turned up no sign of Sidi, and he's considered to be in danger because of his state of health. His case remains unsolved.
