Donna Brock sits in a jail after coming to Satsuma, Fla., a year ago to help search for Haleigh Cummings.

Brock isn't alone. Haleigh's dad, cousin, stepmother Misty and Misty's brother Hank also are in jail. Police arrested all of them on drug charges in January. They're accused of selling prescription pills on the streets of Putnam County.

?Look, they pulled me into the office for two hours to this room before they even brought me to jail,? Brock said. ?They questioned me about where Haleigh is, they think Misty already told me where she's at."

In the jailhouse calls, Brock talks about how detectives think Misty told her what happened to the missing 6-year-old because over the last several months, the two appear to have gotten close.

When Brock came to Putnam County last year, she worked for the group Equusearch. They're trained professionals who travel the country looking for missing kids.

Brock was accused of getting close to Misty for the sake of the investigation and trying to see what, if anything, Misty knew about what happened to Haleigh.

Brock admits on the phone that she gave pills to Misty and that Misty needed them because she was in pain.

"I didn't think it was no big deal, I didn't want them you know what I'm saying?? said Brock. ?I didn't need them, I didn't want them. It was more on my thinking if I just gave these to her, maybe she'll trust me a little bit more."

It's unclear who Brock was talking to on the phone, but the conversation eventually turns to Haleigh and the rumors that the little girl accidentally got her hands on some pills the night she disappeared.
