Dustin Vance Big Medicine, Jr., 24, of Riverton, Wyoming, received a sentence of four months and 11 days in prison and three years of supervised release for assaulting a federal officer. According to court records, on June 4, 2025, a Bureau of Indian Affairs (BIA) officer responded to an incident at tribal housing on the Wind River Reservation involving Big Medicine being violent toward emergency medical services staff. After arresting Big Medicine, the officer was escorting him to a patrol car when Big Medicine spat saliva onto the officer’s ear and face. The BIA conducted the investigation and Assistant U.S. Attorney Kerry J. Jacobson prosecuted the case. Big Medicine was indicted on September 16, 2025, pleaded guilty on December 10, 2025, and was sentenced by Chief U.S. District Judge Kelly H. Rankin on February 18, 2026.

Jacobson prosecuted; Kennedy was indicted on September 16, 2025; pleaded guilty December 5; and was sentenced by Chief U.S. District Judge Kelly H. Rankin on February 20 in Cheyenne.
Christine Holly Jensen, age 55 from Fort Lupton, Colorado received a sentence of over fourteen years—168 months—in prison followed by four years of supervised release for conspiracy to distribute methamphetamine. An investigation into Gerald White of Medicine Bow revealed that White traveled to Jensen’s home in Colorado on February 2, 2025; after returning to Wyoming he was stopped by officers who found about one-and-a-half pounds (670 grams) of methamphetamine in his truck. Jensen admitted she had been selling methamphetamine to White since at least 2023 when arrested at her home in October that year. The case involved cooperation between the Wyoming Division of Criminal Investigation, Drug Enforcement Administration and Albany County Sheriff’s Office.
The United States Attorney’s Office for the District of Wyoming represents the federal government in nearly all litigation within its jurisdiction—including criminal prosecutions for violations of federal law as well as civil lawsuits involving or against the government—and is responsible for collecting judgments and restitution for victims and taxpayers.
Among its community safety programs are Project Safe Childhood—a Department of Justice initiative aimed at combating technology-facilitated sexual exploitation crimes against children—and Operation Take Back America which coordinates DOJ resources nationwide against illegal immigration as well as drug cartels and transnational criminal organizations.
The office also runs a Victim Witness Program intended to ensure victims and their families are treated with compassion and fairness throughout legal proceedings.
