Sgt. 1st Class Gregory McQueen also was reduced in grade to E-1 and given a dishonorable discharge, Fort Hood officials announced Thursday.
McQueen, under questioning by a military judge, explained how he recruited three cash-strapped female soldiers to join the ring. One was told she could make plenty of money at "swinger parties, stripper parties," the Austin American-Statesman reported.
He pleaded guilty to 15 counts as his court-martial began Wednesday, including charges of pandering and conspiracy to solicit prostitution. As part of his plea arrangement, other charges were dismissed, but McQueen still faced one count of assault that the court considered.
Connally, the judge, on Thursday determined McQueen was guilty of the following offenses:
• Four specifications of attempt to pander.
• Three specifications of conspiracy to patronize or solicit a prostitute.
• Three specifications of failure to obey a lawful order or dereliction of duty.
• Two specifications of cruelty and maltreatment.
• Three specifications of adultery or pandering and prostitution.
• One specification of assault consummated by a battery (McQueen did not plead guilty to this charge; Connally found him guilty of the offense).
One of the female soldiers had previously testified that McQueen arranged for her to have sex for $100 with another senior NCO, Master Sgt. Brad Grimes. But prosecutors have said while there were plans for a tryst, the two never engaged in sex. Fort Hood officials haven't indicated whether anyone involved in the conspiracy actually had sex, according to the San Antonio Express-News.
The woman had told investigators she was 20 when she confided in McQueen about money problems after her husband left her and her 3-year-old son and drained the couple's bank account.
She also testified that McQueen had sex with her and took photos of her naked to show potential clients.
Grimes has already been demoted and reprimanded for conspiring to patronize a prostitute and solicitation to commit adultery. Initial charges were filed against McQueen in March 2014.
McQueen was assigned to Fort Hood's sexual assault prevention program and counseled victims of abuse. It's not clear how long he worked with the program.
The case has brought renewed focus on the prevalence of sexual assault in the military. The U.S. Senate last year blocked a bill that would have stripped military commanders of their authority to prosecute or prevent charges for alleged rapes and other serious offenses.
Instructors, recruits and others have been prosecuted in a series of sex-abuse cases at Joint Base San Antonio-Lackland. A Pentagon study released last May on sex assault in the military found that more than 5,000 reports of sexual abuse had been filed in the previous fiscal year, a 50 percent increase from the previous 12 months.
