A former Casper Re-Entry Center employee pleaded not guilty on Friday to charges alleging she had sex with an inmate while she worked at the center.

Tosha Sheesley, 24, entered her pleas in Natrona County District Court to three felonies: two counts of second-degree sexual assault and a count of third-degree sexual assault. If convicted of all three charges she could face up to 55 years in prison.

Sheesley spoke only briefly in quiet tones during Friday’s five-minute hearing, telling Judge Catherine Wilking that she was able to understand the charges against her before entering her pleas with two words.

Prosecutors allege that Sheesley, a former resident manager at the facility, had sex with an inmate at least three times while employed at the facility, according to court documents. All of the intimate encounters took place away from the center.

The documents also allege that Sheesley brought the inmate to her mother’s house and introduced the man as her boyfriend.

Sheesley also admitted to having sex with the man while she worked at the facility, according to the documents. She told investigators that she knew having sex with the inmate was illegal.

Sheesley also told investigators that the sexual contact took place between February and March. Sheesley worked for the re-entry center from Nov. 28, 2016, through March 30, 2017. The inmate was at the facility until March 15, when he was allegedly found with methamphetamine while at the center.

The investigation began when the inmate was arrested in the meth incident. His cell phone was confiscated and messages were found between the man and Sheesley.

Sheesley remained free on bond Friday.

Another former Casper Re-Entry Center employee is facing similar charges that allege she had sex with an inmate while she worked at the facility as a nurse.

Per Wyoming law, it is illegal for an employee of a correctional institution to have sex with any inmate, regardless of age or consent.

The Casper Re-Entry Center is a private company that the Wyoming Department of Corrections contracts with to provide rehabilitation and substance abuse treatment to inmates before they are released from custody.
