Adkins is the boyfriend of Hailey’s mother, Billie Dunn, and the only confirmed suspect in the girl’s disappearance. According to police, Adkins was the last person to see Hailey on December 27: the day she went missing.
According to search warrant affidavits filed after Hailey's disappearance, Adkins admitted to investigators that he threatened the lives of both Billie and Hailey during a domestic dispute.
The three 911 calls, obtained through the Freedom of Information Act, refer to threats made against Billie and her estranged husband, Clint, but not against Hailey. (scroll down to listen to all three 911 calls)
In the first call, made to Colorado City police at approximately 11:30 a.m. on Feb. 14, Billie Dunn told a dispatcher that she was at work in Snyder and feared Adkins was going to enter her home and take something.
Dunn: “My boyfriend and I just broke up yesterday, but he’s saying that he’s going to go in my house and get his t-shirt and I don’t want him in there while I’m gone because I don’t know what he’ll take. I don’t trust him enough to go in there."
Dunn went on to tell dispatchers that she feared Adkins could take a television or her son’s X-Box. Dunn also revealed that she rarely locked the windows or doors.
The dispatcher told Dunn that it was not possible for an officer to stand by her house all day, but said she would inform police.
Three and a half hours later, Dunn made a second call to 911 claiming Adkins threatened her life.
Dunn: “I broke up with this guy a couple days ago and he’s a little ‘MHMR.' He’s telling me that he’s going to kill me and my ex-husband. And it’s going to be remembered for a long time.”
Dunn said Adkins made the repeated threats via text message.
“I texted back just to try and calm him down a little, but he said it’s going to happen.”
In a second portion of the call released to KTAB News, the dispatcher is heard telling the officer that it was Dunn making the request for assistance.
“(She has) been going all day,” the officer replied.
The third call was made from a Snyder police officer to Colorado City police around 4:30 p.m. on the same day, informing dispatchers that he had received a call from Adkins.
Officer: “We got a call over here from her boyfriend say that she’s possible suicidal, threatening to take a bunch of pills."
Dispatcher: “We’ve been having a big problem with those two all day.”
The affidavits signed on Jan. 7 say Adkins originally told authorities that he never threatened Hailey during the dispute, but that he then admitting to threaten the lives of both Hailey and Billie.
