Mexico temple gunman ranted about pyramid's gruesome history to hostages: ‘Don’t move, or I’ll sacrifice you’

A 27-year-old gunman, Julio César Jasso, opened fire at Mexico's Teotihuacan pyramids, killing a Canadian tourist and injuring 13 others. Jasso, who was obsessed with Adolf Hitler, claimed the attack was timed to mark the 27th anniversary of the Columbine High School shooting and Hitler's birthday, and threatened to sacrifice victims during the incident. He later died by suicide.
