The first and only female Air Force military training instructor to undergo a court-martial in connection with the sex scandal at Joint Base San Antonio-Lackland was found guilty Thursday.

Staff Sgt. Emily J. Allen was found guilty of having unprofessional relationships with four technical training students.

A military judge sentenced Allen to three months confinement, reduction to the grade of E-3 (Airman First Class) and hard labor without confinement for 30 days.

The court-martial was the 18th to be held against Air Force military training instructors at Lackland.
