May 2, 2017 Double Homicide Suspect in Custody

Flagstaff, AZ – The Coconino County Sheriff’s Office has obtained a criminal complaint and arrest warrant for a 29-year-old Grand Junction, Colorado man alleging he committed the May 2, 2017 double murder of a Williams, AZ couple.

Derrick Shawn Barnett had been identified by Sheriff’s Deputies and Detectives as a possible suspect in the murder of 67-year-old Michael Dimuria and his 64-year-old wife, Nora Dimuria. The couple’s home had been rummaged through and their Jeep missing from the property.

Coconino County authorities worked with several agencies in Colorado to include Dolores County, Montezuma County and the Mesa County Sheriff’s Office, as well as the Cortez and Grand Junction Police Departments to locate the suspect.

Dolores County Sheriff’s deputies located Dimuria’s Jeep abandoned at a campground in Dove Creek, Colorado around midafternoon Friday, May 5, 2017.  Barnett was located and arrested by the Dolores and Montezuma County Sheriff’s deputies and the Colorado State Police around 9:00 PM Friday after a 30-mile-high speed chase. Sheriff’s deputies recovered some property they believed may be evidence in the case.

The criminal complaint charges Barnett with the murders, theft of a means of transportation and misconduct involving weapons. Barnett is currently in custody at the Montezuma County Jail in Cortez, Colorado facing local charges. Coconino County will seek extradition of Barnett back to Arizona.
