You know the 18-year-old who was stabbed to death last night the Fruitvale BART station? Well, it turns out he was killed in self-defense. The two assailants, it seems, had the tables turned on them after robbing a 23-year-old out-of-towner last night. According to Chron, the victim "managed to grab a knife from one of the assailants and stabbed the other one to death." Oops. The victim/assailant has been identified as Christopher Gonzalez, who, after being knifed, "ran into [his] home, cried out for his parents and sister and collapsed in his father's arms." So, be careful when you're out there trying to steal from us civilians, muggers. It's a dangerous world out there.
