BAKERSFIELD, Calif. (KGET) -- After Marian Schultz was found guilty of drunken driving in a crash that left a motorcyclist unable to walk without assistance, his defense counsel requested he be given a competency evaluation. Another trial was held in which a judge determined Schultz was competent, and on Tuesday he was sentenced to six years and four months in prison -- bringing an end to a case that has stretched on for more than five years. 15-year-old suspect in deadly Marketplace shooting surrenders: Bakersfield PD Schultz, 32, was found guilty of two felony DUI counts in December of last year. In April 2019, prosecutors say, Schultz did "donuts" in his pickup truck across all four lanes of a Bakersfield roadway. He pulled to the curb, and a motorcycle and car approached. Schultz then hit the gas and darted across the road intending to perform another donut -- hitting the motorcycle and car, according to the District Attorney's Office.
