Accused of smuggling fentanyl into a jail in her rectum and distributing it to others, a 22-year-old Riverton woman could face up to 23 years in prison.  

Desiray Yvonne Marsh was charged Thursday with taking controlled substances into a jail, which is a felony punishable by up to three years in prison and $3,000 in fines. She also was charged with unlawful delivery of fentanyl, which is punishable by up to 20 years in prison and $25,000.   

The Blues 

On Sept. 30, Fremont County Sheriff’s Sgt. Matthew Weber was told by a woman in the Fremont County Detention Center there was fentanyl in her jail pod. The inmate said Marsh had several fentanyl pills “inside of her,” according to an affidavit filed Thursday in Lander Circuit Court.  

Marsh, the inmate said, had given the pills to another inmate who became sick from ingesting them. 

Jail staff conducted a “shakedown” search of Marsh’s pod to find the fentanyl; they removed inmates from the area, questioned and strip-searched them.  

Marsh reportedly admitted that she had drugs “on her,” and she surrendered four blue pills to a deputy searching the pod. She also admitted to having given another inmate a pill, the affidavit says.  

Jail staff found 85 blue pills in the pod during their search that later tested positive for fentanyl.


On Oct. 4, another female inmate called her mother and said she had been put on lockdown because Marsh brought fentanyl into the jail. The woman told her mother that she had helped remove a pill-filled plastic bag from Marsh’s rectum. They then shared the pills with several inmates in the pod, the woman said, and she herself consumed one, the affidavit reads.   

Marsh’s prosecution is ongoing.
