Investigators in San Antonio say Sgt. Wade Allen Perkins and Sgt. Kimberly Epperson have a detention hearing Thursday. Both were arrested Tuesday as part of an investigation involving the military, local officials and the FBI.
The abuse allegedly happened while the soldiers were at Joint Base San Antonio-Fort Sam Houston. A criminal complaint says images of the boy being abused and other activities were as part of the couple's sexual activity.
Both soldiers have been charged with production of child pornography.
Investigators say Perkins, currently now stationed at Fort Hood, has since married someone else.
The boy has been placed in protective custody.
