A federal judge on Tuesday sentenced a former Los Angeles County sheriff’s deputy to 18 months in prison for conspiring to violate the civil rights of a 23-year-old skateboarder.

Christopher Hernandez is the second former sheriff’s deputy sentenced to prison in connection with the case of Jesus Alegria, who accused the two deputies of kidnapping and abusing him after he yelled at them to stop picking on teens in a Compton park. The deputies forced Alegria into the back of their cruiser minutes before crashing the vehicle while chasing another man, prosecutors said, then fabricated a drug arrest to cover it all up.
