This is a gruesome and sad tale: A man in his 30s or 40s took a taxi at 9:30 Saturday morning to a freeway overpass along I-580 at Airway Boulevard in Livermore, made the cab stop, got out, went over to the guardrail, sat on it facing the road below, leaned forward, and dropped off to his death. The CHP subsequently shut down two lanes of 580 for about two hours. Police are still looking for the cab company and driver, who has not come forward. [Bay City News/Tribune]
