ELBERT COUNTY, Colo. — An Agate man was sentenced Tuesday to 144 years in prison for the death of a former partner in a marijuana business and then setting a wildfire to cover it up.

An Elbert County jury on July 19 found Shawn Geerdes, 48, guilty of murder in the death of Jason Dosa, 44 of Parker.

“You had a horrible criminal history,” judge Jeffrey Holmes told Geerdes in imposing the sentence.

The case began Sept. 20, 2015, when Jefferson County sheriff’s deputies were notified of a fire. They found a car on fire that had started a wildfire.

Ultimately, investigating officers found a body in the trunk, later identified as Dosa. He had been shot five times.

Investigators traced Dosa’s movements and found his last location at a marijuana greenhouse in Agate on land owned by Geerdes.

Dosa and Geerdes were former partners in the grow operation.

Investigators found evidence at the grow house including bloodstains and spent shell casings that indicated Dosa had been killed there and his body later taken to Jefferson County.

Geerdes was found guilty of second-degree murder, setting a wildfire and second-degree arson.
