LISBON — Three Columbiana County Jail inmates were let out of their sentences early in August after one of them was severely beaten and the others were threatened. The three are represented by attorney Lawrence Stacey II, who says the threats came from fellow inmates who wanted his clients to smuggle drugs and cigarettes into the jail. He is contemplating filing a negligence lawsuit on their behalf against county commissioners and CiviGenics Inc., the private company that operates the jail under contract with commissioners. The three inmates are: — Jeffrey B. Woodburn, 38, sentenced to four months in jail for domestic violence. — Michael Lentini, 39, sentenced to 100 days for domestic violence. — Jonathan McGarry, 19, sentenced to six months for assault. The charges were misdemeanors, and Stacey said all three had work release privileges at the outset of their sentences, which means they were allowed to leave the jail to go to and from their jobs.
