A Louisiana sheriff’s deputy was fired after he allegedly coerced a wanted woman into performing a sex act on her infant son in exchange for not arresting her.

Iberville Parish Sheriff’s Deputy Shaderick Jones, 42, was arrested and terminated immediately Friday after police became aware of a video he filmed of the disturbing incident, The Advocate reported.

The mother, Iyehsha Todd, 26, claimed Jones told her he wouldn’t arrest her last week on an open warrant for a traffic ticket if she performed the sex act.

Investigators believe that Jones was off duty at the time of the incident, according to The Advocate. He allegedly said that it was “his fantasy” and recorded the sex act on his cellphone.

“He had been off duty for 30 minutes,” St. Gabriel Police Chief Kevin Ambeau told the newspaper.

A search warrant was executed on Jones’ home Friday night and authorities confiscated several electronic devices.

“I have 30 years of experience,” Ambeau said. “This is at the top of the list for the worst case. I have never witnessed something so disgusting — it’s sickening to your stomach to see.”

Jones was booked into West Baton Rouge Parish Detention Center on charges of rape, malfeasance in office and pornography involving juveniles.

Todd was arrested and booked into Iberville Parish jail, where she faces charges of rape and incest, according to officials.
