Samuel Bontrager was 23 when he was found dead in San Francisco on May 16, 2008. He sustained fatal stab wounds while driving near Mission and Otsego Avenues. The case has remained open and cold for many years with few leads and no confirmed motive; authorities have described the circumstances as consistent with either a random act of violence or a targeted attack.

The San Francisco Police Department’s Homicide Detail has appealed to the public for help. The Mayor’s Office has authorized rewards ranging from $50,000 to $250,000 for information in cold cases like this one, and law enforcement has urged anyone with information to contact the SFPD or use anonymous tip lines.

Does anyone with knowledge of the area or that night have details that could help move this investigation forward?
