Charges Filed in Gilpin County Homicide

Jeffrey Maynard

First Judicial District Attorney Pete Weir announced that charges have been filed against Jeffrey Mason Maynard, DOB: 11-10-91, in the death of 63-year-old John Cumby. Mr. Cumby’s body was found in a remote campground in Gilpin County in September, 2017.

Maynard has been charged with two counts of First Degree Murder; Aggravated Robbery; two counts of Identity Theft; Motor Vehicle Theft; Theft and one Violent Crime count.

On September 11, Mr. Maynard was arrested following a traffic stop in Ada County Idaho. He was driving a van which was registered to Mr. Cumby. According to the arrest affidavit, Ada County Sheriff’s deputies found several items belonging to Mr. Cumby in the van. Through the course of their investigation they spoke with Mr. Cumby’s family in Illinois and learned that he had not been heard from since August 20 and was overdue in returning in Illinois.

The investigation in Idaho resulted in the Ada County Sheriff’s deputies contacting the Gilpin County Sheriff’s Office on September 11. The Gilpin County Sheriff’s Office began their investigation with the assistance of the Colorado Bureau of Investigation (CBI), the Jefferson County Sheriff’s Office, and the District Attorney’s Office.

On September 13, the Gilpin County Sheriff’s Office, with the assistance of the Jefferson County Sheriff’s Department K-9 Unit and the Front Range Rescue Dogs Association, located the remains of Mr. Cumby in a camping area in Rollinsville, in Gilpin County.

Mr. Maynard was transported from Idaho to Gilpin County on December 28. At his first appearance on December 29 he was advised of his rights and of the charges which have been filed against him. He is due back in court in Gilpin County on January 3 at 1:30.


The filing of a criminal charge is merely a formal accusation that an individual has committed a crime(s). A defendant is presumed innocent until and unless proven guilty. See Colo. RPC 3.6.
