A mother has been sentenced to 15 years to life in prison for driving her son and his friends to a California skate park to kill a 13-year-old gang rival.

Judge Arthur Jean sentenced 31-year-old Eva Daley on Tuesday for the revenge killing of Jose Cano last year in Long Beach. Daley was convicted of second-degree murder in October.

She claimed she didn't know what her passengers were planning. Prosecutors say she may have sought revenge for an attack on her son or an incident when the rival gang threw flares at her apartment complex.

The teen accused of the fatal stabbing is serving the same sentence as Daley. Daley's son and five other youths admitted to manslaughter and are serving time at juvenile facilities.
