Douglas County, CO — In what is being referred to as an "ambush style" attack, a Colorado deputy was tragically killed New Year's Eve by a delusional gunman. Although the attack was called an 'ambush' in the media, the shooter, Matthew Riehl live-streamed the attack before which he is heard telling deputies to go away.

Late Sunday afternoon the deputy who lost his life was identified as 29-year-old Douglas County Sheriff's Deputy Zackari Parrish. He was described as a veteran law enforcement officer, and leaves behind a wife and two children. Along with Parrish, four other deputies were shot, as well as two civilians.

The incident began early Sunday morning when deputies showed up to Riehl's apartment to talk about a restraining order he wished to file against his domestic partner.

Instead of ambushing the officers, Riehl refused to cooperate with them, did not answer their questions and demanded to see a warrant when they asked to come inside. After Riehl refused to let them in, he then shut the door after telling them he was going to bed.
