Police are searching for the gunman who shot two people on a boat at the Venice Marina in Sheepshead Bay Sunday.

Witnesses say the victims were standing on a boat when an argument erupted. The gunman then allegedly stepped on board and opened fire. One man was killed when a bullet struck him in the face and the other man died after he was shot in the chest and fell into the water.

Police are hoping several surveillance cameras in the area will help them in their investigation.
