With his own mother testifying against him, a man accused of slitting his wife’s throat because he believed she snitched him out to the law may be looking at a quarter-century behind bars.

Jurors returned a guilty verdict against Andrew Billings, 53, who was tried Tuesday for the attempted murder of his wife, Adrianna Billings who was found bleeding beside Allen Ferry Road on April 4, 2017. He is charged with attempted first degree murder.

“(Blood) was everywhere,” testified Chief Deputy Robert Patrick of the car where the slashing occurred, noting they also found a bloody knife inside the vehicle – the knife they believe Billings used to slash his wife’s throat.

Mr. Billings was located in Sparta shortly after his wife was rushed to Erlanger for treatment of the deep cut in her throat. It was at that time officers found the blood splattered car. “There was a bloody palm print on the door,” Patrick noted, adding they found locks of the victim’s hair and blood all over the car and on her husband’s clothes.

Lawmen were able to pinpoint how Mr. Billings got the knife used in the assault thanks to a call from Cheryl Roberts out of Crossville. She told officers that Mr. Billings showed up at her door before the cutting and came in for a visit. She said it seemed odd since she had not seen him in five years. She noted that when he left there was a large butcher knife missing. She would later identify the blood stained butcher knife used to slice Mrs. Billings’ throat as the one the defendant had taken.

Prosecutors next played a tape where the defendant confessed to the crime. The interview was conducted shortly after the incident and a tearful Andrew Billings took the blame.

“Nobody else had anything to do with it,” he said on the video tape, uttering the words “thank God” when he was told his wife was going to survive.

The final nail in the coffin in the case was hammered in when the defendant’s mother, Patty Manning said her son had pledged to kill his wife if she turned him in on meth charges.

“He said if she turned him in, he would kill her,” Manning told the jury, adding the couple had been at her house before the incident and had fought in front of her for six hours. She also said her son appeared to be on meth at the time, adding he had asked her to turn off the TV because he thought the FBI was spying on him through the television set.

He will face 15 to 25 years in prison when he is sentenced Sept. 20.
