Firearm Offenses

Jeffrey Cletus Geist, 58, of Gillette, Wyoming, was sentenced to 18 months’ imprisonment, with three years of supervised release to follow for being a felon in possession of a firearm.

According to court documents, on March 12, 2024, the Campbell County Sheriff’s Office stopped Geist on his motorcycle for a traffic violation. A canine was deployed on the exterior of the motorcycle and immediately alerted to the presence of narcotics. Deputies located three bags of methamphetamine and a 9mm handgun.

“Geist is a previously convicted felon and is prohibited from possessing a firearm,” the release said. Geist was indicted on Sept.18, 2024 and pleaded guilty on Dec. 18, 2024. Chief U.S. District Court Judge Scott W. Skavdahl imposed the sentence on March 11 in Casper.

The Bureau of Alcohol, Tobacco, Firearms and Explosives and the Campbell County Sheriff’s Office investigated the crime. Assistant U.S. Attorney Christyne Martens prosecuted the case.

Joshua Roye Dunn, 36, of Sheridan, Wyoming, was sentenced to 36 months of supervised probation for being in possession of an unregistered firearm. The Bureau of Alcohol, Tobacco, Firearms and Explosives and the Sheridan Police Department investigated the crime. Assistant U.S. Attorney Paige Hammer prosecuted the case. Dunn was indicted on July 18, 2024, pleaded guilty on Dec. 13, 2024, and Chief U.S. District Court Judge Scott W. Skavdahl imposed the sentence on March 26 in Cheyenne.

Drug Trafficking and Illegal Reentry of a Previously Deported Alien

Cesar Antancio Torres-Cazares, 36, of La Piedad, Michoacan, Mexico, was sentenced to 24 months’ imprisonment with three years of supervised release for possession with intent to distribute cocaine and time served for illegal reentry into the United States. He will be deported following his imprisonment.

According to court documents, in November 2023, the Wyoming Division of Criminal Investigation began investigating a cocaine drug trafficking organization in the Jackson, Wyoming, area. Agents conducted a controlled buy from Torres-Cazares, which led agents to his residence, where they found large quantities of cocaine and proof of distribution. After he was arrested, Immigration and Customs Enforcement was contacted because Torres-Cazares is not a U.S. citizen, had previously been removed from the U.S., and had not applied for permission to reenter.

DCI and ICE investigated the crime. Assistant U.S. Attorneys Seth Griswold and Cameron J. Cook prosecuted the cases. U.S. District Court Judge Alan B. Johnson imposed the sentence on March 26 in Cheyenne.

In addition to the term of incarceration, Wolfley was placed on 3 years of unsupervised probation, terms of which include a ban from Yellowstone National Park during that period and was ordered to pay $3,050 in fines and court costs.
