This looks like a pretty good summary article.
Hailey Dunn was 13 when she disappeared. What happened in the hours before is a mystery with several different stories.

Billie Dunn says the last time she saw her daughter Hailey was on an early morning a few days after Christmas.
"I was on my way to work, so just peeking in her bedroom, seeing her in the bed," Billie tells Crime Watch Daily. "She was completely home alone while I was going to be at work for my 12-hour shift. Her father did live right across the street so I assumed she was going to get up and go over there."
But when Billie returns home later that night, Hailey isn't around. Billie says her live-in boyfriend Sean Adkins is also back from work and tells her that Hailey went to stay the night at a friend's house nearby.

In the missing-person investigation, police turn to those closest to Hailey: Mom Billie, and her live-in boyfriend Shawn Adkins, and Hailey's dad Clint Dunn, who lives down the block. All of three have almost daily interactions with her.
As the investigation deepens, Hailey Dunn's home life is revealed as anything but normal.
"She loved her family. So home life seemed to be very simple, but the further we started learning about her family, things seemed to be different behind closed doors," said Guinn. "We got word about a lot of alcohol, a lot of partying from her mother, and so you got the sense that maybe home life was a little harder than what they let on."
And Billie Dunn and Shawn Adkins are on police radar even before Hailey's disappearance.
"About 10 months before Hailey went missing there was a call to police, a domestic disturbance," said Guinn.

Friends, neighbors and police comb the fields around town for any sign of missing 13-year-old Hailey Dunn. But her mother Billie never joins the search party.
And what about her live-in boyfriend, Shawn Adkins?
"He wasn't involved in foot searches at all," said Billie. "He really didn't even help me pass fliers and things. I think he just wanted to stay out of the spotlight."
Police are so concerned that they ask both Billie and Shawn to take polygraph tests. Billie does so willingly. But she says she was shocked when she got her results.
Billie took two polygraph tests. According to a police affidavit, she was under the influence of narcotics when she sat down for the first test. So days later she sits down again, and the outcome is a shocker.
"I was told by the DPS interviewer that gave it that deception was indicated," said Billie.
Neither Billlie Dunn nor police will say on exactly which questions she showed deception. But the results make cops dig deeper. And according to the affidavit, a search warrant uncovers an alarming trove of disturbing literature in the house. Police found Billie and Shawn had collected pages and pages of articles printed from online content, all of it profiling serial killers. Among those was material about serial killer George Banks, convicted of 13 murders, including five of his own young children.

But then it was her boyfriend Shawn Adkins's turn, and when cops hook him up to the polygraph machine, everything changes.
"The first two times he failed, got up and walked out," said CBS7 News Anchor Tatum Guinn, who's covered the story.
On the third try, investigators say, he shows deception. But the test indicates that Adkins is telling the truth on two bombshell questions that could break this case wide open.
"They asked him pointedly, 'Where can we find Hailey?' He said somewhere in Scurry County," said Guinn. "They asked him, 'Who should we be looking at in this?' And he said 'You should be looking at us' -- meaning Shawn and Billie."
Scurry County is about 20 miles north of where Hailey was last seen.

And then in March 2013 a break in the case: A hiker comes across a skull and a femur bone at Lake J.B. Thomas, a remote area about 20 miles north of Hailey's home.
