A man who viciously beat and bit his grandmother until she managed to flee to a neighbor's house pleaded guilty to three felony charges Friday as part of a plea bargain.

David Aaron Wilson, 25, pleaded guilty to aggravated abuse of an elder adult, a second-degree felony, and violation of a no-contact order, a third-degree felony. He also pleaded guilty to a separate second-degree felony DUI charge.

In return, prosecutors and defense attorneys asked 3rd District Judge Stephen Henriod to dismiss charges of tampering with a witness and aggravated assault, both third-degree felonies; a class B misdemeanor charge of interfering with an arrest; and a class C misdemeanor charge of intoxication.

Henriod ordered a presentence report.

The grandmother, 68, told her daughters that Wilson had been watching a movie about a cannibalistic serial murderer and that he had become "Hannibal," according to a letter provided to prosecutors.

Wilson and his mother were taking care of the grandmother. However, two other daughters of the victim expressed fears that Wilson and their sister were taking advantage of the woman.

Those daughters also said their mother had been left in serious pain after Wilson's attack in her home on Sept. 22, 2007.

"My mother told me that he beat her until she stopped screaming and he thought she was dead," the letter read. "She said that he tried to poke her eyes out, bite her eyes out and bite all of her fingers off. He bit her arms, head, face, finger, etc. He would bite her then spit on her — over and over again. He kicked her in the teeth and chest, sat on her and crushed her chest, punched her in the face multiple times and choked her."

Wilson is being held in the Salt Lake County Jail on a no-bail order and is scheduled to be sentenced in May.
