The April death of a veteran killed after a night out in the Boston Theater District is getting national attention.

"America's Most Wanted" is airing this new cell phone video from the night Stephen Perez died. It shows an all-out brawl involving Perez and several other men in a parking garage.

Police say the fight started after something was said to Perez and his friends as they were leaving. They responded and then punches were thrown. At one point, a man in the video shows a gun.

Surveillance video shows the same suspect running out holding that gun. He's been identified as Peter Castillo.

Boston police posted the video on their website and say he fled to the Dominican Republic.

Perez served two tours in the Middle East as a sniper for the Army.
