BERNE, Ind. (WPTA21) - An Adams County man who said he stabbed his girlfriend dozens of times has taken a plea deal.

Austin Griffith was charged with the murder of 34-year-old Kayla Bentley. He admitted to stabbing her to death on Sept. 12, 2019, at her Berne home.

Griffith pleaded guilty but mentally ill to murder according to court documents filed earlier this week.

The plea agreement calls for Griffith to serve 65 years with 10 years suspended.

If the judge accepts the plea deal, Griffith would serve a total of 55 years behind bars for the crime and serve 10 years of probation.

The victim died of her injuries on the way to the hospital. The coroner ruled her death a homicide.

During an interview at the Adams County Detention Center, detectives said Griffith admitted to stabbing Bentley multiple times.

Griffith said Bentley had a god or a monster living inside her that was “terrorizing him.”

He said “I had to stop the sick god. I had to stop it or humanity was at risk.”

Griffith went on to say the so-called monster living inside Bentley would say things to provoke him, and at one point, it became too much for him.

“So, I stabbed her to death," Griffith told detectives.

Griffith said he was acting on behalf of his god, Satan, and that “My god, Satan, blessed her with no pain.”

When he was taken into custody, he said he “I lost control” and “oh my god, what did I do?”

This wasn’t the first time police were called to this address.

On Sept. 2, 2019, police were called to their apartment.

Griffith at the time told police he was tired of Bentley accusing him of cheating, and wanted her out of the apartment.

Detectives said there were no accusations of violence at that time.

Griffith has a history of abuse.

He was previously convicted of theft, domestic battery, and burglary.

Griffith is scheduled to be sentenced on Nov. 4.
