A fugitive wanted by the US Marshals Service was arrested this week in Rock Springs. 30-year-old Darren Matthew Olson, of Rock Springs, was wanted by federal authorities after he allegedly went missing from a supervised-release. Olson was indicted by a federal grand jury for his role in conspiring to possess and to distribute heroin in the Sweetwater County in 2014, which resulted in the overdose death of a local man. The investigation into Olson also resulted in the arrest of 5 other area residents and 2 people from Utah, on similar charges. Olson was sentenced to 41 months of incarceration in 2015, but was released from prison in 2016, with orders to serve 4 years of supervised-release. Olson is believed to have violated the terms of his release on at least 5 separate occasions in the last 3 months, including an arrest for DUI. Due to the violations, the court revoked his supervised release earlier this month, and issued a warrant for his arrest. Olsen was taken into custody on Tuesday without incident. He now faces an additional 36 months in federal custody. Picture of Olsen courtesy of the Sweetwater County Detention Center, click to enlarge.
