On the morning of December 31, 2017, Deputy Zackari Parrish, 29, was shot while responding to a verbal disturbance at the Copper Canyon Apartments in Highlands Ranch, Colorado. Deputies had checked the apartment earlier that morning and found no crime, but returned around 5:15 a.m. after another call reporting a domestic disturbance. The male subject, Matthew Riehl, barricaded himself in a bedroom and opened fire through the door with a rifle, reportedly discharging more than 100 rounds in an ambush-style attack.

Deputy Parrish was struck multiple times; an autopsy later showed 11 gunshot wounds. Three other deputies, a Castle Rock police officer, and two civilians were also wounded. Continuous gunfire prevented immediate rescue of Parrish; a regional SWAT team eventually entered. Riehl, a 37-year-old veteran, was shot and killed by law enforcement at the scene; Parrish later died at a hospital. Parrish is remembered as a husband and father of two young children and a committed officer.

Did anyone in the area see or hear the events that morning who hasn’t yet spoken to investigators?
