Surveillance video shows Martinez and Larrama exchanging words and investigators later learned that Larrama had denied Martinez and his friend entrance, the prosecutor said. Martinez and his friend walked away but were pursued by Larrama, the prosecutor said. The video then shows Martinez raising his left hand as if to defend himself, then striking Larrama in the head with an aluminum beer bottle, before Larrama stabbed the victim in the chest, the prosecutor said.

Martinez was taken to a hospital where he was pronounced dead. He had recently been discharged after a four-year tour in the Marines, authorities said.
