Mistrial declared in Douglas County case involving death of a Colorado State Trooper

Douglas County District Court Judge Shay Whitaker declared a mistrial Thursday in case against the truck driver accused of hitting and killing a Colorado state trooper in 2016.

Forty-one-year-old Noe Gamez-Ruiz was initially charged with careless driving causing death and failure to yield for the accident last Nov. 25.

Authorities say Trooper Cody Donahue was standing beside a vehicle and investigating a previous crash when he was hit on Interstate 25 south of Castle Rock.

In January of 2017, his charges were upgraded to criminally negligent homicide, carelessly passing an emergency vehicle resulting in death, and careless driving resulting in death. Gamez-Ruiz pleaded not guilty earlier this year.

A new trial is scheduled to begin in February 12, 2019. A motions hearing is set for October 26 at 3 p.m.
