This means Kalvin Cardenas will not stand trial as scheduled next week.
Police say the 24-year-old grabbed the girl as she rode her bike to school in Central Fresno. Cardenas was arrested and charged with kidnapping and sexual assault in September 2012 after a standoff in Clovis.
His attorney told Action News that Cardenas realized he could not deny what he had done because he recorded much of it to video. He faces a maximum sentence of life without parole. Cardenas is scheduled to be sentenced in May.
