An Oklahoma man was arrested on Friday after police say he conspired to carry out rape on an unborn baby upon the infant’s birth, with a pregnant woman he met on Facebook.

KOCO reports that Daniel Thomas J. Deffner, 39, of Canadian County, was reportedly exchanging messages with a Midwest City woman on Facebook about when and where to sexually assault her unborn child once she gave birth. He reportedly told the woman in detail about his twisted fantasies of torturing and raping a baby, and she allegedly agreed to not only let him carry out his sick plans on her own baby after birth, but she also agreed to participate with him.

The Midwest City Police Department gathered evidence from the duo’s Facebook conversations and sent the information over to the Canadian County Police Department.

“This is one of, if not the sickest things I’ve ever heard of,” Canadian County Sheriff Chris West told KOCO. “I can’t describe the evil and deranged details of what they were planning to do to this innocent and defenseless baby.”

The pregnant woman had other children, who are now in the custody of the Oklahoma Department of Family and Children’s Services.

During the investigation, authorities found evidence that Deffner also received nude images from an 11-year-old girl. West stated that Deffner somehow manipulated the young girl into sending him the photos and had plans to meet her in person at a later date.

“It sickens me to no end that an 11-year-old girl spent any amount of time alone with such a sick and demented individual as Deffner. I pray that baby wasn’t scarred for life,” West said.

Deffner was arrested on a complaint of possession of a controlled dangerous substance, possession of drug paraphernalia, and procuring a minor in child pornography. He hasn’t been charged yet, as police are still looking for additional evidence and victims. The Midwest City Police Department arrested the pregnant woman, whose name is still unknown at this time. It’s also unclear what charges she faces.
