Pretty sure Billie was quoted in MSM saying that, and also said she'd gone to SA's grandma's house with a couple of Texas Rangers in the hopes that he'd talk to her, but no dice.
Yes, this was the "pulling teeth" interaction with Nancy Grace. When asked by Nancy, BD said she hand't asked SA about what he was doing 12/27 a.m. when his cell pings put him in CC. BD said that she hadn't had a chance to ask him because "they" wont' let her to talk to him when she calls. Nancy pushed. "They" became his his lawyer. BD then mentioned that she'd gone with a Ranger to confront him in-person but they were turned away.
NG TRANSCRIPT 1/18
GRACE: What do you see in that scenario, Billie Dunn? What`s he doing back around your home?
DUNN: I don`t know. That`s all stuff I need a lot of answers to, that we all need a lot of answers to.
GRACE: Well, have you tried to ask him?
DUNN: No.
GRACE: Why?
DUNN: I haven`t spoke with him. He`ll send a text every now and then. But I haven`t asked him, why did you come back to the house? He never let me know that. I didn`t know that until the affidavits came out and showed his pings. That he had come back here first, then to Big Spring.
GRACE: Well, why haven`t you asked him?
DUNN: I haven`t spoke with him.
GRACE: Yes, I know that. My question is, why? I would want to know why. What were you doing back around my house?
DUNN: I want to know too.
GRACE: Well then why haven`t you asked him? Oh, because did the cops tell you not to talk to him?
DUNN: I`m not allowed -- no. When I call over there, they don`t let me talk to him. They won`t put him on the phone.
GRACE: What about a cell phone?
DUNN: He doesn`t have a cell phone.
GRACE: So when you call over there, what do they say?
(CROSSTALK)
GRACE: Well, text him.
DUNN: That Shawn -- Shawn can`t talk to you.
GRACE: He can`t talk to you or he won`t talk to you. Because obviously he can still speak.
DUNN: Per his lawyer, he can`t talk to me.
GRACE: So his lawyer -- man, that was like pulling a tooth. His lawyer has told him not to talk to you?
DUNN: (INAUDIBLE).
GRACE: It`s OK. His lawyer has told him not to talk to you?
DUNN: Right.
GRACE: Why?
DUNN: I don`t know. There`s a lot of questions I have and I guess that`s why. Also, I have gone over there with Texas Rangers to try to get him to come talk. Shawn, you need to talk. It`ll just be two guys. There`s a lot of answers you can provide. And that`s probably why they`re not wanting me to talk to him.
