Wilson was moved to solitary confinement in August while reports of the relationship were investigated.
According to court papers, Gonzalez was seen by other inmates going in and out of Wilson's cell starting in March, meeting him in a vacant activity room next to his cell when other inmates were supposed to be sleeping.
"I took a chance because I was so vulnerable and wanted to be loved and now I am carrying his child," Gonzalez said, according to court papers.
She said she "kind of got sucked into his world," and that she "felt like, well, why not give him a child as far as giving him some kind of hope."
She confessed her relationship with Wilson to a different boyfriend, another inmate who had been under her supervision at the federal prison but is now housed at a state facility. She said it was over with Wilson, and that she was worried she would get into trouble.
After she became pregnant, Wilson's mother made contact, requesting a sonogram photo, according to court papers. Gonzalez said she was worried about the calls because she feared authorities would catch her.
"I know what's to come. I know what is going to be said about me," she said, according to court papers. "How am I going to explain this to this little boy? Mommy was in the military ... Mommy was a C.O., Mommy got wrapped up ... And then the opposite end is with a person who took lives. So how do you explain that?"
