BAKERSFIELD, Calif. (KGET) -- A jury has found that Bakersfield police and a probation officer did not use excessive force or were negligent during a 2020 arrest. The jury returned its verdict in a trial held last month in federal court, according to court filings. What we know about the search for escaped killer Cesar Hernandez Matthew Alan Hearn said he suffered a concussion and scrapes to his head when police stopped his vehicle and arrested him on Chester Avenue north of West Columbus Street. In his lawsuit, Hearn said a police officer twisted his arm and dragged him from the vehicle, using "unnecessarily excessive force," after Hernandez questioned why he was pulled over. Tangled in his seat belt, Hearn asked to remove it but the officer twisted his arm and shoved him against the car to handcuff him, according to the suit. Hearn said the probation officer -- who also took part in the stop -- falsely accused him of spitting at her and officers placed a spit mask on him, “further humiliating him and restricting his liberties without legal justification,” according to the suit.

Prosecutors charged Hearn with four misdemeanors — including two counts of battery on a peace officer — and two infractions in connection with the traffic stop. A judge acquitted him of all charges, court records show.
