The trial of Allan Ray Andrade begins today, accused of killing transgendered teen Angie Zapata.Police say Allen Ray Andrade, 32, snapped when he learned that 18-year-old Angie Zapata, who was born Justin Zapata but lived as a young woman, was biologically a man.
Andrade admitted to investigators that he beat Zapata first with his fists and then with a fire extinguisher, according to a Weld County arrest affidavit obtained by ABCNews.com.
He allegedly told investigators he thought he "killed it," referring to Zapata, before hitting her again with the fire extinguisher as she tried to get up, the affidavit says.
Zapata's body was discovered by her sister on July 17, 2008, inside her Greeley, Colo., apartment. She had been fatally beaten, with blunt force trauma around her head, according to the Weld County Coroner's Office.
