A Yukon felon has been charged with a felony for allegedly striking an emergency room nurse and security officer at the Yukon hospital.

Katherin Alyse Retter, 29, was charged Dec. 16 in Canadian County District Court with assault and battery on emergency medical technician.

Yukon Police investigated the case. The charge stems from an incident in July at Integris Canadian Valley Hospital, 1201 Health Center Parkway.

About 1:30 p.m. July 8, Lt. Mike Walker responded to the Yukon hospital on a report that Retter had assaulted a nurse.

Allegations against the defendant are outlined in a probable cause affidavit signed by Det. Dave Carroll.

“The defendant knowingly and willfully deposited / transferred bodily waste on medical personnel (ER nurse) while the defendant was being treated at the emergency room,” the court document shows.

“The defendant then knowingly kicked the ER nurse during another attempt to treat the defendant. The defendant then left the room, causing a disturbance within the ER area and was restrained by security. The defendant struck the security officer several times in the head and body causing injuries to his arm and redness to his face.”

Upon arriving at the ICVH emergency room, Lt. Walker noticed a patient screaming out profanities and insults to the hospital staff.

Retter was “screaming and flailing about” while the alleged victim was checking her vital signs.

When the ER nurse tried to start an IV and treat the defendant, Retter allegedly spit in the nurse’s face and kicked the nurse in the chest.

It was the second time Yukon Police has responded to ICVH that day.

Yukon police officer Tomy Tran had been dispatched to the hospital at 8:48 a.m. July 8 on a reported disturbance involving Retter.

Retter reportedly tried to run out of the emergency room while “cussing and screaming”, according to the court affidavit.

She was irate and not listening to the hospital security officer’s commands, the document indicates.

When the security personnel tried to wrap his arms around Retter to restrain her, she allegedly started “throwing her arms around” and struck him in the head.


Defendant Retter has previous felony convictions and charges pending in several other criminal cases.

Offenses in Oklahoma County District Court include: Assault and battery on a police officer, placing body fluid upon a government employee, public intoxication, obstructing an officer, possession of a controlled dangerous substance, and possession of drug paraphernalia.

A felony charge of attempted second-degree robbery is pending against Retter in Oklahoma County.

Retter pleaded guilty in 2018 in Canadian County District Court to the felony charge of prisoner placing body fluid on government employee. She received a two-year deferred sentence (except for 15 days in the county jail) in that case.
