Jonathan Marvin cried tearfully and proclaimed his innocence before a judge sentenced him to 50 years to life in the 2007 killing of Eric Martin of Pittsburg, a fellow marijuana cultivator to whom he owed $10,000, according to a Contra Costa Times report.
Marvin, 36, is a former assistant football coach at Benicia High School. During the trial, jurors learned that he was a construction worker and former football coach on disability, struggling to support his wife, four children, and pregnant girlfriend. Like Martin, 30, Marvin starting growing marijuana on the side, and Martin fronted him $10,000 when Marvin's own pot crop went bad.
Prosecutor Harold Jewett said Marvin killed Martin because Martin was hounding him for repayment. Jewett asserted that Marvin lured Martin to a parking lot off North Broadway, in an area near Walnut Creek's car dealerships and main post office. There, Jewett says, Marvin shot him. Martin's body was found slumped in the driver's seat of his Acura sedan the morning after the shooting.
