Wrinkle says the inmate is now in a state prison. The Missouri Department of Corrections alerted him on Feb. 28 that the inmate and the nurse may have been “romantically involved.”

The Corrections Department has audio recordings and other documentation, which it furnished to Wrinkle. He asked the Missouri State Highway Patrol to investigation the inmate’s allegations, and a detective interviewed the nurse on March 18.

“The investigation to this point has substantiated the allegations,” Wrinkle wrote in a news release on Tuesday.
