On Jan. 24, 2010, four years ago this Friday, 83-year-old Huan Chen was attacked as he left a San Francisco Municipal Railway light-rail stop at Third Street and Oakdale Avenue to walk to his nearby assisted-living facility, police said.
The attack involved a group of five teens, who hit Chen on the back of the head, causing him to fall and strike his head on the pavement. He was taken to a hospital where he succumbed to his injuries two months later, according to police.
The teens fled after the beating and have still not been identified. The mayor's office is offering a $100,000 reward for information leading to their arrest and conviction.
Anyone with information about the case is urged to call homicide Inspector Mike Morley at (415) 553-1145, the Police Department's anonymous tip line at (415) 575-4444 or to send a tip by text message to TIP411.
