The New Mexico State Police Investigations Bureau learned that East had shot his girlfriend, and then dragged her out of the residence during a domestic dispute. He was then allegedly shot by another man at the residence.
East was pronounced dead at the scene, according to police. His girlfriend was transported to a hospital in Albuquerque where she was in stable condition as of Tuesday.
East, the brother of former UFC fighter Cody East, competed 21 times as a professional MMA fighter from 2009 to 2016, according to MMA Junkie, a news website that covers mixed martial arts.
Nicknamed “The Beast,” his professional MMA record was 15-6-0.
He was knocked out by Brian Heden in his final fight at Legacy FC 60 in October 2016.
East also has a history of run-ins with the law, reports said.
