Early on the morning of May 6, 2011, a 38-year-old man was stabbed in the abdomen by an unknown male assailant while walking through Crissy Field, an area within Golden Gate NRA. On October, following a lengthy investigation, an arrest warrant was obtained from the United States District Court in San Francisco for a 33-year-old man for assault and attempted murder. He was arrested later that month and held in federal custody. On January 26th, on the advice of his defense counsel, the man pled guilty to assault with a deadly weapon. Based on the nature of this case and the man’s past criminal history, he was sentenced to 41 months in federal prison and three years of supervised release. This case was investigated by the Criminal Investigations Branch of the Park Police’s San Francisco Field Office. The lead investigators were detective sergeant Robert Jansing, detective Robert Reidy, and investigator Steven Polianos.
