The maximum time that he can get is one year on a parole violation. They might make him an offer for less than a year if absconding is the only violation.
Seniorjudge: California has determinate sentencing, meaning every crime carries a determinate sentence, which the defendant must serve in full (minus credits), after which he is subject to a mandatory parole period of 3 years (5 years for sex offenses.) If the defendant violates parole, he can be returned to custody for a maximum of one year. Murder and a few other crimes carry indeterminate terms, and for those offenses the parole board decides when they get out, and when they do they are on parole for life.
