San Francisco prosecutor won't charge man accused in 2013 baseball game stabbing

Prosecutors have decided not to prosecute a man in the stabbing death of a Dodger's fan during an altercation after a Los Angeles-San Francisco baseball game last year.

District Attorney George Gascon said in a statement Friday that prosecutors wouldn't file charges against Michael Montgomery because they didn't believe they had enough evidence to prove that Montgomery didn't act in self-defense when he killed Jonathan Denver.

Gascon said it is not clear how the Sept. 25 incident began.

Police have said Denver and his group, many wearing Dodgers garb, got into a shouting match over the Dodgers with Montgomery and his group — at least one of whom was wearing a Giants cap.

Montgomery's father said his son was jumped and stabbed Denver in self-defense after they yelled "Giants suck."

Denver's brother disputed that Montgomery acted in self-defense.
