Staff Sgt. Timothy J. Hall, 31, offered guilty pleas to charges of fraternization, obstructing justice and violating an order at his court martial at Marine Corps Recruit Depot.
Hall, who was tried in San Diego, was also found guilty of adultery after one of his victims – now a lance corporal at Camp Pendleton – testified he fondled her and made her have sex with him in 2007 on the floor of a recruiting office in Wisconsin. Hall was on a recruiting tour in Wisconsin, according to the Marines.
Hall was sentenced to one year in prison, reduction to the lowest enlisted rank and a bad-conduct discharge.
Due to a plea bargain, the prison term will be limited to four months.
