OKLAHOMA CITY -- An Oklahoma man has been arrested for first degree murder, after reportedly killing his wife.
Jimmy Hankins, 56, spoke with homicide investigators on Friday.
According to a probable cause affidavit, he confessed to killing his wife, Susan Willingham-Hankins, because he 'did not want to take care of her anymore.'
"Mrs. Hankins had been suffering from a number of health issues," said MSgt. Gary Knight, with Oklahoma City Police.
Court records explain that Hankins confessed to doubling his wife's dose of Xanax, took her off thyroid medication, disconnected her oxygen, then suffocated her with a pillow.
"He was arrested on a complaint of murder in the first degree," said Knight.
Susan Hankins' death, in July of last year, was originally believed to have been from natural causes.
What led Mr. Hanks to allegedly turn himself in remains unclear. The affidavit includes a quote, where Hankins states:
"I knew what I did. I knew what I did was premeditated. I knew she could have lived, and I took that from her."
Hankins is in the Oklahoma County Jail, but has not yet been formally charged.
