A Brooklyn-raised Marine sergeant and his new bride were tortured and killed execution-style in their California home - allegedly by four other Marines under his command.

Sgt. Jan Pawel Pietrzak, who was raised in Bensonhurst, and his wife, Quiana, were found bound and gagged in the ransacked house, each shot in the head.

Pietrzak was the suspects' sergeant at Camp Pendleton, Quiana's mother said Wednesday.
