A 33-year-old man was sentenced yesterday to 15 years to life in state prison for driving under the influence of alcohol and crashing into motorcyclist who later died, the Los Angeles County District Attorney's Office announced.

At Tuesday's court appearance, defendant George Edward Allison Jr. (dob 12/6/82) of Long Beach, pleaded no contest to a felony count of gross vehicular manslaughter while intoxicated in case VA138009.

Allison also admitted he was previously convicted of driving under the influence of alcohol in Orange County in 2005, 2009 and 2013.

The defendant was immediately sentenced and remanded into custody following his plea. Deputy District Attorney Andrea Mader, who prosecuted the case, said on Jan. 5, 2015, Allison was driving under the influence of alcohol when he struck motorcyclist Jerry Frey on the eastbound 91 Freeway in Cerritos.

The collision launched Frey's body about 100 feet and the victim landed on the freeway, the prosecutor said. Good Samaritans went to the victim's aid and Frey was taken to the hospital for medical treatment. Meanwhile, Allison was arrested in connection with the collision, the prosecutor said.

Three weeks after the crash, Frey, 60, succumbed to his injuries and died, according to the prosecutor.

The case was investigated by the California Highway Patrol.
