KILLEEN, Texas—According to his own lawyer, military prosecutors are investigating accusations against a Ft. Hood sergeant once assigned to an artillery battalion at Ft. Hood, the nation’s largest military base.

Joseph Jordan told CNN that his client, Sgt. First Class Gregory McQueen, was suspected of “pandering” and that a military prosecutor had said McQueen is under investigation for prostitution. Jordan told CNN his client would “fight the charges” but also acknowledged that a military prosecutor had offered McQueen a deal, “if he would give up other members of the prostitution ring.”

No formal charges have yet been announced against McQueen but the incident is one of a string of recent accusations of sexual misconduct that have rippled through the American military. Most recently, an enlisted man at West Point was accused of taking photographs of women cadets while they were taking showers.

The program director of a woman’s shelter here in Texas told CNN that her organization had more than 1,000 domestic violence or sexual assault cases in 2012 and about a third of them involved soldiers at Ft. Hood. Suzanne Armor said that many women soldiers were fearful of reporting assaults because they were concerned such reports might adversely affect their military careers.

CNN Correspondent Drew Griffin will have more on these allegations tonight on AC360 at 8 p.m. ET.
