A Spring Valley man was convicted yesterday in a non-jury trial on six felony counts stemming from several incidents while he was locked up in the Rockland County Jail. Rockland County District Attorney Tom Walsh says 34 year-old Darius Williams was twice caught with contraband, and he assaulted Corrections Officers on two separate occasions. Williams is scheduled to be sentenced in March next year. He faces up to seven years in state prison on each count of Second Degree Assault, Criminal Possession of a Weapon, and Promoting Prison Contraband. Williams had been imprisoned after he was convicted in July of assaulting a random passerby in the Village of Haverstraw.
