Mason Mayer, the younger brother of Google executive Marissa Mayer, has not been in San Francisco long. But in that short time, he has eased into the ranks of the city’s moneyed socialites, appearing with the glitterati at society events like the opening of the San Francisco ballet, Manus Salzman Valentine’s Ball in 2010 and this year’s Midwinter Gala at the Legion of Honor on March 10.

He has also earned a criminal record, after prosecutors charged him with three felonies for allegedly beating up his-then girlfriend and threatening to throw her off the Golden Gate Bridge during a September argument in his condo at the Four Seasons, the same building in which his sister owns a reportedly $5 million penthouse.

Mayer, 33, was arrested by SFPD on November 28, 2011, on suspicion of felony domestic violence, assault, and false imprisonment according to booking records. District Attorney George Gasc??n charged Mayer with three felonies, according to documents obtained by the SF Appeal, and a judge issued a stay-away order in January for Mayer to keep away from his alleged victim, Kelli Ann Trent, 30.

According to court documents, Mayer and Trent attended a September 24 house party at Mint Plaza, before which Mayer allegedly pregamed with “2 or 3” vodka and Red Bulls.

SFPD Inspector Michael Becker wrote in an affidavit that while there, Mayer became angry when a bartender gave Trent a glass of water. The couple argued over another woman, also at the party, with whom Mayer had allegedly cheated on Trent, and Mayer was also “angry” at Trent for talking with Zach Bogue, Marissa Mayer’s husband and Mayer’s brother in law, “whom [Mayer] dislikes,” Becker wrote.

The couple returned to Mayer’s apartment at the Four Seasons. Once in his bedroom, Mayer locked the door, allegedly threw Trent down, spit in her face, “pull[ed] her hair out and pull[ed] off her eyelashes” before pulling her by her hair and slamming her head into the marble floor of the bedroom, Becker wrote.

With Trent on the floor “in the fetal position,” Mayer allegedly punched her eight times and told her “the only way she was going to get out of this was if he drove her to the Golden Gate Bridge and she jumped off,” according to the affidavit.

The alleged beating stopped when a friend of the couple rang Mayer’s cell phone from outside the apartment. Mayer let him in, and the friend, now a witness in the case, told Becker he stayed the night “to make sure nothing else would happen,” according to the affidavit.

Trent later told cops that she was afraid of Mayer’s family.

Photos obtained by the Appeal of Trent’s injuries, allegedly at Mayer’s hands, appear to reflect the some of the damage described in the affidavit as “the (victim’s) left eye was black and blue, the inside of the (victim’s) left eye was red, the left side of the (victim’s) face was swollen, the (victim’s) right hand was bruised and the (victim’s) left arm was scratched and red.”

A warrant was issued for Mayer’s arrest in November. The police report and other information in domestic violence cases are sealed under state law.

Though the District Attorney’s office can’t offer comment on an ongoing case, spokesperson Stephanie Ong Stillman was quick to point out that domestic violence cases like this one are a high priority for their office.

“Domestic violence is a serious and dangerous crime that knows no economic, sexual or racial boundaries,” Stillman said. “People in our community should know that domestic violence will not be tolerated in San Francisco.”

When contacted by the Appeal, Trent declined to speak on the record.

Attempts to contact Mayer through his attorney, Gilbert Eisenberg, were not successful. Eisenberg did not return multiple messages left Tuesday and Wednesday at his Montgomery Street office.

Mayer has reportedly not worked since his sister’s company went public, though in addition to attending exclusive parties, he has donated generously to Democratic political causes: he contributed $35,800 to the Obama Victory Fund on April 25, 2011, and dished out $30,400 to the Democratic National Committee on November 8, 2010, according to records. He gave a downtown Minneapolis address — 500 East Grant Street, a new condominium building — and listed himself as self employed in “finance.”

He is next due in San Francisco Superior Court on April 18 for a pretrial conference.
