POCATELLO, Idaho – A Douglas County Sheriff’s Office deputy played a key role in the arrest of 32-year-old James Marting of Pocatello for Coercion and Enticement of a Child for Sexual Activity under the age of 18. The deputy, Mackenzie “Mack” Miller, was part of an undercover operation involving the Douglas County Sheriff’s Office, Idaho Internet Crimes Against Children (ICAC) Task Force, Homeland Security Investigations (HSI), and the Pocatello Police Department.

“I am incredibly proud of Deputy Miller for his exceptional work on this case,” said Sheriff Dan Coverley. “His dedication to protecting children and his commitment to bringing predators to justice reflects the high standard of professionalism we strive for at the Douglas County Sheriff’s Office.”

The investigation began on January 25, 2025, when Deputy Miller, serving as an HSI Reno Task Force officer, engaged in an online conversation with Martin. Posing as a 13-year-old girl, Deputy Miller documented Martin’s unlawful communications, which ultimately resulted in Martin arranging a meeting with the child persona.

On February 13, Martin arrived at a prearranged location in Pocatello, Idaho, where he was arrested by HSI Idaho Falls, HSI Reno, the Douglas County Sheriff’s Office, the Pocatello Police Department, and the Idaho ICAC Task Force. The arrest was made without incident.
