Adam Li, a 26-year-old Chinese-American man from San Francisco, was last seen on September 15, 2016. He was reported on 45th Avenue between Fulton and Cabrillo Streets in the Richmond District; at the time he lived in the Sunset District. He is 5 feet 7 inches and about 145 pounds. When last seen he wore a white button-down shirt, black pants, a black apron, and black and white Converse shoes.

Li suffered from bipolar disorder and depression, and his family said he had poor social skills and could become frightened and run if approached suddenly. His phone briefly pinged near 42nd Avenue and Clement Street after he disappeared, then was turned off and produced no further leads. The San Francisco Police Department and his family have not developed significant information about his whereabouts.

Does anyone who knew Adam or was in the Richmond or Sunset areas on September 15, 2016 have information that could help investigators?
