SAN ANTONIO -

One more military training instructor and alleged victim are involved in the investigation into sexual misconduct among instructors and trainees at Joint Base San Antonio Lackland.

That brings the total number if MTIs involved to 25.

Of those, five have been court-martialed and convicted; six are facing charges, and 14 remain under active investigation.

The total number if victims stands at 49.

"The numbers, we have said from the beginning, will go up and down as this investigation continues," said Brent Boller, who works in public affairs for the 502nd Air Base Wing/JBSA.

The revelation of an increase in the numbers comes the day before an announcement from the Pentagon on the findings of a command-directed investigation.

Hundreds of trainees and instructors were interviewed, roughly 18,000 surveys taken and several focus groups conducted as part of that investigation, said Boller.

On Thursday, an Article 32 hearing is scheduled for another embattled MTI.

Staff Sgt. Donald Davis is accused of aggravated sexual contact and assault and battery of one trainee and having a 'wrongful, unprofessional, personal or sexual relationship' with another trainee.

An Article 32 hearing is similar to a civilian grand jury proceeding. It will determine whether Davis is referred to court martial, or military trial.
