More than a year after his conviction, a one-time gay porn star who beat his former girlfriend over the head with a toilet tank lid has been sentenced to 12 years in state prison for attempted murder.

Sacramento Superior Court Judge Troy L. Nunley imposed the term Wedneday on Marc Anthony Donais, 46, who established a reputation in the 1990s as one of the top stars in his genre under the name of Ryan Idol.

According to the victim’s testimony at trial, Donais entered the woman’s apartment the night of Sept. 5, 2009, and told her, “I came over here to kill you.” The two had been involved in a relationship, but the woman — whose name is being withheld because she is a domestic violence victim — said she cut it off when she caught him having sex with his male lover.

The woman said Donais stormed into her bathroom while she was taking a bath of her 48th Street residence and began to beat her with the porcelain lid until “I felt blood gushing down my shoulders.”

Donais’ sentencing had been delayed since his September 2011 conviction so his attorneys could prepare a motion for new trial that Nunley ultimately denied.
