For the second time this month, a uniformed military official whose job was to prevent sex abuse has come under investigation for a sex crime. Agents from the Army's Criminal Investigation Division were looking into allegations that an Army sergeant first class at Fort Hood, Texas, sexually abused females in his unit and ran a prostitution ring on the base. Officials said that the soldier, who was not identified, had been assigned as an Equal Opportunity Adviser and Sexual Harassment/Assault Response and Prevention (SHARP) program coordinator at Fort Hood with the Army's III Corps when the allegations surfaced. The CID investigation was looking into allegations that the sergeant was involved in abusive sexual contact, pandering, assault and maltreatment of subordinates" in his oversight of a unit of about 800 soldiers. The allegations against the sergeant surfaced a week after Lt. Col. Jeffrey Krusinski, branch chief of the Air Force's Sexual Assault and Prevention Office, was arrested and charged by Arlington County, Va., police for allegedly being drunk and groping a woman in a parking lot near a strip club one mile from the Pentagon. Krusinski has been charged with sexual battery, and a hearing on his criminal case has been set for July. The charges against Krusinski rocked the Air Force, which was already dealing with numerous courts-martial stemming from the alleged abuse of female recruits at Lackland Air Force Base, Texas. .
