Keisuke Koizumi, a 22-year-old Japanese student, was last seen on April 23, 2008, in San Francisco, California, where he was attending a language school. He left his hotel room, telling his roommate that he was going to deliver a computer monitor to a friend, but he never returned. All of his belongings were left behind in the hotel room he shared with another student.
There are concerns that Koizumi may have been suffering from depression at the time, and he was possibly taking anti-depressant medication. He was last seen wearing a white long-sleeved t-shirt, a gray argyle sweater, a light-colored olive green jacket, blue jeans, and white Converse sneakers. Despite investigations, no further details about his whereabouts have surfaced, and he remains missing. The San Francisco Police Department continues to handle the case, but very few leads have been developed since his disappearance.Last Seen: Apr 23, 2008
