Body found in Wyoming ID'd as missing Lafayette man; 2 held in murder case

LAFAYETTE, Colo. - Lafayette Police have confirmed the body found in eastern Wyoming Thursday is Nathaniel Tallman, a Lafayette, Colo., man missing since late January.

Two people have been arrested in the case.

"After an incredibly thorough investigation two arrests have been made in the case.  The two arrested parties are identified as Russell Britton, 58, who is being held at the Boulder County Jail with no bond, and charged with first-degree murder," a police statement said.  "Also under arrest is Moises Cazares Mendez, 26, who is being held at the Las Colinas Detention Facility in San Diego, California for first-degree murder with a $1 million bond."

Lafayette police say the 25-year-old Tallman was last seen on Jan. 23 when he drove from home in his 2014 Mitsubishi Lancer Ralliat. The car found abandoned on Feb. 13 near Foothills Highway and South Boulder Road in Boulder.

Then on Thursday, police say a body was discovered just north of Lusk, Wyoming. The Wyoming Division of Criminal Investigations processed the crime scene and notified Lafayette Police Department of the discovery.

By all accounts, Nate Tallman, a high school baseball star, had been happily getting a good start in life while working with his father. He was in the process of moving to a new house in the mountains and had bought a new car, which still had the temporary tags on it.

Tallman's family has offered a $10,000 reward for information on the missing man.

The Lafayette Police Department asks anyone with information about this case to call the police tip line at 303-604-8014 or email
