She Called Deputies to Report a Fight With Her Son. The Investigation Led to Incest Charges.

It started as an ordinary domestic violence call. On August 21, deputies in Polk County, Florida were sent to a home in Lakeland after a woman said her son had hit her. By the time the investigation was over, both the woman and her son were in jail — charged with incest.

According to the Polk County Sheriff's Office, Christina Clemens, 46, called deputies and said her 22-year-old son, Shane Clemens, had battered her. Deputies reported seeing injuries to her palms, and Shane admitted to pushing her, according to the sheriff's office.

But while deputies were looking into the domestic violence complaint, Shane told them something else: that he and his mother had been in a sexual relationship since he turned 18, according to Sheriff Grady Judd.

Deputies went back to question Christina about what her son had said. According to Sheriff Judd, she confirmed the relationship — and when asked how often, she told deputies they'd had sex "only about 100 times."

That figure comes directly from Christina's own statement to deputies, as relayed by the sheriff's office to reporters. It has not been independently verified beyond what she told investigators, and it has not been tested in court.

"What else can you say? That's nasty. And it's illegal," Judd said.

Investigators also spoke with Christina's husband, who lived with her. He told deputies he had no idea his wife and stepson were sexually involved — though he said he'd noticed the two of them going into the master bedroom together and locking the door, according to the sheriff's office.

Shane was booked on August 21 on charges of incest and domestic violence battery. He's being held without bond.

Christina was booked six days later, on August 27, on charges of incest and living in open adultery. She's being held on $5,250 bond. Incest is a third-degree felony under Florida law.

As of now, neither Christina nor Shane has a reported plea or trial date. The allegations — including the account of how long the relationship lasted and how often it happened — are based on statements to investigators, not findings from a judge or jury. Both are presumed innocent unless and until a court says otherwise.
