SACRAMENTO (CBS13) — A former gay porn star was convicted Wednesday of attempted murder in the attack of his girlfriend two years ago, according to Sacramento County District Attorney Jan Scully.

Marc Anthony Donais, 45, was also found guilty of assault with a deadly weapon, battery causing serious bodily injury and domestic violence. He faces a sentence of 15 years in prison. Sentencing is scheduled for Dec. 9.

Donais is a former model and adult film star under the screen name of Ryan Idol.

In September 2009, he went to his then girlfriend’s home on 48th Street to confront her about his suspicion that she was cheating on him.

Donais punched the victim repeatedly in her bathroom, causing her to fall to the floor. While she was on the ground, Donais took the lid off of the toilet and slammed it down on her head. The impact shattered the lid and caused severe lacerations to the victim’s head.

According to his Wikipedia entry, Donais appeared in “Playgirl” magazine in 1989, which launched his career in adult films. He retired from the porn industry in 1996 and established himself as a credible stage actor.
