An Air Force colonel will face a court-martial in late March on a charge of three counts of sexual assault, a spokesperson for Joint Base Andrews, Md., told Task & Purpose.

Col. Sean McNamara, a member of the 316th Medical Support Squadron at Andrews, is accused of groping the breast and genitals of an unidentified woman without her consent, according to a charge sheet provided to Task & Purpose.

The alleged incident took place on or about Dec. 4, 2019, at or near Leesburg, Va., according to the charge sheet. The Air Force began investigating the colonel that month after the alleged victim spoke to a Sexual Assault Prevention Response advocate, a spokesperson with Joint Base Andrews said. The information was then turned over to the Air Force Office of Special Investigations, and the case went to an Article 32 preliminary hearing for review prior to the Air Force charging McNamara on Oct. 2, 2020.

At the time of the alleged assault, McNamara was commander of the 39th Medical Group, based at Incirlik Air Base in Turkey, Air Force Times reported. He was moved to 11th Medical Support Squadron at Andrews in January 2020, and then to the 316th in June, Air Force Times reported. He is a pharmacist who entered active duty in January 2003.

“The Air Force takes allegations of misconduct very seriously regardless of rank,” said Maj. Jessica Tait, a public affairs officer for Joint Base Andrews, in a statement. “However, Airmen are presumed innocent until proven guilty in accordance with due process.”

The colonel’s court-martial is set to begin March 29.
