Kyle Man Sentenced to Federal Prison for Stealing Checks

RAPID CITY - United States Attorney Ron Parsons announced today that U.S. District Judge Camela C. Theeler has sentenced a Kyle, South Dakota, man convicted of Larceny. The sentencing took place on April 20, 2026.

Lyle Dean Misun Tibbits, 33, was sentenced to one year in federal prison, followed by three years of supervised release. He was further ordered to pay a $100 special assessment to the Federal Crime Victims Fund and $9,880.00 in restitution.

Tibbits was indicted for Larceny by a federal grand jury in November 2025. He pleaded guilty on January 9, 2026.

In June 2025, Tibbits, while working on a ranch in Kyle, stole several blank checks belonging to his employer. Between June and July 2025, he unlawfully wrote several checks totaling nearly $10,000.00 to himself and another person and then cashed the checks and used the proceeds for his own personal gain.

This matter was prosecuted by the U.S. Attorney's Office because the Major Crimes Act, a federal statute, mandates that certain crimes alleged to have occurred in Indian Country be prosecuted in Federal court as opposed to State court.

This case was investigated by the Oglala Sioux Tribe Department of Public Safety. Supervisory Assistant U.S. Attorney Benjamin Patterson prosecuted the case.

Tibbits was immediately remanded to the custody of the U.S. Marshals Service.
