ADAMS COUNTY, Colo. — The man found in a vehicle with the body of his ex-girlfriend in a 2011 incident was found guilty of first degree murder, kidnapping, and sexual assault by an Adams County jury Friday.

On March 24, 2011 Westminster police officers responded to the 11000 Block of Stuart Street on a suspicious vehicle with black trash bags taped to the inside of the windows. 

Police found a dead woman in the vehicle with Christopher Mainock, who investigators say had self-inflicted injuries.

The woman was later identified as 20-year-old Sarah Barroga-Hulett.

Prosecutors say Mainock, who was in a previous relationship with Barroga-Hulett, used chloroform to subdue his ex-girlfriend and drag her to his vehicle.

Then he forced her to disrobe in the back seat of his car where he sexually assaulted her and stabbed her to death, according to a news release from the district attorney’s office.

During the investigation, detectives found a knife, a bottle of chloroform, twine, a full tank of gasoline and matches in Mainock’s car.

Court documents show the jury dismissed Mainock’s insanity defense and found him sane at the time of the crime.

Mainock faces life in prison without parole for the murder of Barroga-Hulett. Sentencing is scheduled for March 15.

“I am very pleased that justice was served for Sarah Barroga-Hulett,” said   District Attorney Dave Young.  “Our thoughts and prayers go out to her family.”
