LIVERMORE — A Livermore woman faces 67 criminal charges for allegedly having sex with two teen boys.

Police arrested Christine Shreeve Hubbs, 42, on Thursday evening on a warrant. She is being held at Santa Rita Jail in Dublin in lieu of $4.3 million bail.

The mother of one of the boys went to Livermore police on July 27 to report she found a nude photo of Hubbs on her son’s cell phone, according to court records. The boy told police the sex acts with Hubbs began in December 2008, when he was 14.

He told police he met with Hubbs multiple times for sex acts and twice went with her to a hotel to have sex with her. The boy said the relationship continued until January 2010.

During the investigation, police learned of a second boy, who is now 14, who said he had a sexual relationship with Hubbs from December 2009 through July.

Investigators say Hubbs communicated with the teens by text messages and at times used her cell phone to send sexual messages and nude pictures of herself.

According to court records, the boys said she gave them gifts, mostly gift cards, and money, and drove them in her black, 2006 Hummer to various locations in Livermore and elsewhere in Alameda County to engage in sexual activity.

Hubbs learned of the investigation and retained a lawyer, Sarsfield said. Police have not yet interviewed her.

She is scheduled to be arraigned Monday afternoon at the Gale/Schenone Hall of Justice in Pleasanton.

In a separate case, Hubbs was also charged on Thursday with four counts of contributing to the deliquency of a minor and one count of discharge of a BB gun, Those charges relate to a June 29 incident when a bicyclist reported being shot by an Airsoft projectile by boys in a black Hummer.The biker recognized Hubbs as the driver from her personalized license plate.

Hubbs told police she was driving and heard the boys pulling the gun triggers as she drove through town. The boys in the car admitted to the shooting but said Hubbs did not try to stop them.They said she had bought them the guns.
