Fresh details are out in an affidavit that shows where investigators believe evidence exist inside phone records from both Billie Dunn, Hailey's mom, and her boyfriend, Shawn Adkins.
As each day passes, authorities continue to intensify their search.
""The criminal aspect of it, in the investigation, is intensified," said Colorado City Manager Pete Kampfer.
"We've done hundreds of interviews and follow up interviews," added Sr. Trooper Sparky Dean, of the Texas Department of Public Safety.
Two weeks have past and still very few answers for the question "Where is Hailey Dunn?"
Details in a request for a search warrant, show investigators found alarming evidence inside a box in Billie Dunn's closet, graphic articles about mass murders, serial killers, sexual sadist, murders of family members and other topics that both adults consider "hobbies."
On HLN's "Nancy Grace" Dunn attempted to explain these statements.
"They were stories I thought I was interested in reading."
When asked about what she's thinking about this point, Dunn replied, "Right now, it's not a good feeling to me."
After a long pause Dunn added, "I'm scared to death that somebody hurt her."
In a separate line of questions, Grace asked Dunn if she questions her boyfriend.
"That bothers me," responded Dunn, who was cut off when Grace asked, "Is that a yes? Dunn: Yeah."
Also in the affidavit, a conversation reported to police from Hailey's uncle about Adkins, where the uncle asked if anyone could do something to Hailey.
Adkins reportedly answered "Yah, it's like a killing a deer."
The uncle explained that Adkins has talked before about killing deer and cutting them with a chainsaw.
While these references are raising alarm for some, the reality is a mother is still without her daughter.
"Somebody knows where she is," said Billie Dunn.
In the investigation, police obtained search warrants last week to look inside a white Chevrolet Lumina that both Dunn and Adkins have access to.
Other elements in the affidavit list a 2010 incident where Adkins threatened to kill both Billie and Hailey.
