Billie Dunn, the mother of missing Colorado City teen Hailey Dunn admits she's beginning to lose hope.

This comes after Billie Dunn was arrested Thursday and affidavits obtained exclusively by KTXS on Friday show that authorities found more pornography, including child porn, on devices used by Shawn Adkins, Billie's former live-in boyfriend.

After Billie Dunn was arrested and interrogated, she said she is now doubting Adkins' innocence. Billie Dunn was arrested for misdemeanor charges not directly related to the Hailey Dunn case.

Billie Dunn told KTXS, "There's so much that's happened, so much that I found out about him. I think about 'Did he have time to hurt my daughter?' and 'Why would he hurt her?'"

Since being released from jail Friday on three misdemeanor charges, Billie Dunn said she has filed a no-trespassing order against Adkins.

Billie told KTXS, "I tried to stand by him at first because I really felt like I knew him. I knew he wouldn't hurt Hailey, and why would he. But after I talked to investigators, it puts doubt in my mind."

Clint Dunn, Hailey's father, said when he heard about Billie's arrest, he feared that it had to do with his missing daughter.

Clint told KTXS, "Initially, I was concerned that, you know, she was being arrested for something with Hailey."

The 13-year-old Hailey Dunn has been missing for nearly three months, making it hard for both her parents to stay positive.

Billie Dunn says it is getting harder. "I'm not as hopeful as I had been," she said. "It really does get harder. I didn't think it could, but it does."

Clint Dunn says he will never stop looking for his little girl but knows others may. "They can only search for so long, so I'm not sure how much longer the search will go on," he said.

Clint Dunn told KTXS that he now is working to get Hailey's face even farther out of Texas into the rest of the nation.
