Deputies say Walters and the other male then got into a fight before the male stabbed Walters with a pocketknife, reportedly in self-defense.
Investigators said Walters had been harassing his ex since their breakup in 2018. She obtained a protection order against him that deputies say he has violated multiple times. He was arrested in January for violation of the protection order, investigators said.
Walters was taken to Huntsville Hospital, where he remains in the Intensive Care Unit.
