Indiana police have arrested a man and accused him of shooting his wife after recording her begging for her life, according to PEOPLE.

The Journal & Courier reported that Patrick Elliott, 50, allegedly shot his wife, Donita Elliott, 47, in their Lafayette home on August 8. According to an affidavit, Patrick originally told officers that he was forced to defend himself after Donita brandished a knife.

However, cellphone footage, supposedly shot by Patrick, showed him firing the fatal shot followed by Donita begging her husband for help, the affidavit revealed. Though Patrick called 911, Donita was pronounced dead at the hospital.

Tippecanoe County Sheriff Barry Richard told reporters that police were at the Elliott residence for more two hours for a domestic dispute a day before the fatal shooting. Reports indicate that officers left after they deemed the situation stable.

Investigators also say they are baffled as to why Patrick didn’t delete the incriminating video.

Patrick also allegedly told police that his wife suffered from mental health issues. A day before his arrest, he allegedly penned a letter to his church detailing these mental health issues.

“Monday evening she left in a rage, and a few hours later returned home and made a decision that unfortunately left me in a life or death situation,” Patrick wrote to the Lafayette Reformed Presbyterian Church, The Journal & Courier reported.

“I chose life, and unfortunately my choice included her death. I will wear that burden and guilt forever, even though I know God knows my heart, and that I am already forgiven.”

On Tuesday, prosecutors charged Patrick with murder, providing false information, and use of a firearm in connection. His trial scheduled for November 21.
