Sheridan Man Arraigned for Telephonic Threats and Property Destruction

A Sheridan man was arraigned for two charges at a hearing Tuesday in Fourth Judicial District Court. Sheridan Media’s Ron Richter has the details.

On August 26 and 27, 47-year-old Cory Gagner made numerous death threats via telephone and slashed or punctured all four tires of the alleged victim’s vehicle. At Tuesday’s arraignment hearing, Gagner pleaded not guilty, and not guilty by reason of mental impairment or deficiency to the charges of felony property destruction and misdemeanor unlawful telephonic threats.  A mental health evaluation of Gagner will be conducted by the Wyoming State Hospital.

District Court Judge Darci Phillips scheduled a three-day jury trial to begin Monday, February 22, 2027. A pretrial conference will take place January 21 at 9:30 am. A request to modify Gagner’s bond was denied by the Court due to the nature of the charges and the threat that he poses to the community. He is currently being held at the Sheridan County Detention Center on a $15,000 cash only bond. If convicted, he faces up to 11 years in prison and fines of up to $11,000.

Also from District Court:

A Sheridan woman pleaded guilty to a felony drug possession charge and admitted to violating her probation at a hearing Tuesday in Fourth Judicial District Court. At the hearing, District Court Judge Darci Phillips accepted the terms of the plea agreement reached with the State and sentenced Toni Oleson to 2 ½ to 4 years in prison for the underlying 2024 conviction for felony drug possession, and 2 ½ to 4 years in prison for the recent drug possession charge from July. The sentences will run concurrent to one another and Oleson will receive credit for any time served of presentence confinement.

The possession charge was prosecuted as a felony because Oleson has had five prior drug possession convictions, with the latest conviction being her sixth offense since 2019. Three or more drug possession convictions in Wyoming is considered a felony offense. Oleson was ordered to pay $300 in court costs and assessments and was remanded to the custody of the Sheridan County Detention Center pending transfer to a location to be determined by the Wyoming Department of Corrections.
