(KCEN) -- A soldier stationed at Fort Hood beginning in 2011 is now in FBI custody.
He is accused of using his girlfriend's three-year-old son to make child porn.
The woman was also allegedly part of the abuse.
An arrest affidavit says Sgt. Wade Perkins and Sgt. Kimberly Epperson were stationed at Fort Sam Houston when they began abusing the woman's three-year-old son.
Perkins was then re-assigned to Fort Hood, where he allegedly requested sexual photos and videos of the boy sent to him via text message from Epperson.
After being questioned by the FBI, Perkins admitted to molesting the boy.
Both suspects are in FBI custody.
