A doomed young couple found shot to death and burned beyond recognition in a car at a Bronx park were victims of a deadly gang war sparked by a stolen purse, law enforcement sources told The Post.

Nikki Huang and ex-college hoopster Jesse Parrilla, 22, were executed in a series of retaliatory shootings that erupted after Huang griped to her gangster pals that a rival crew mugged her last Sunday, stealing her handbag, the sources said Thursday.

Parrilla was not a part of deadly beef between the rival Up the Hill and the Down the Hill crews, the sources said — and only wound up getting mixed up in the bloodshed while spending time with Huang.
