SCURRY COUNTY, Texas - Law enforcement remain mum on the probe into the death of Colorado City teen Hailey Dunn, whose remains last week were identified as those found in March near Lake JB Thomas in Scurry County.
"Nothing today," said Katherine Gilkinson Chaumont, spokeswoman for the FBI in Dallas, when asked for an update and when the ex-middle school cheerleader's remains will be released to her family.
A Big Spring man who came across the teen's remains recently told KTXS that he found a skull, a tooth and a femur, along with blue warmups that Hailey Dunn, then 13, was believed to have been wearing when she disappeared in late December 2010.
Earlier this week, Gilkinson Chaumont said the Scurry County Sheriff's Office, Texas Rangers and FBI – along with other agencies – are jointly working the investigation.
Efforts to reach Scurry County Sheriff Trey Wilson for comment have been unsuccessful. A representative of the Scurry County Sheriff's Office suggested contacting the FBI for comment.
The FBI continues to urge anyone with information into Hailey Dunn's death to call the Dallas FBI at 972-559-5000 or the Crime Stoppers tipline at 1-800-252-8477.
Meanwhile, Hailey Dunn's mother still hasn't been questioned by law enforcement since her daughter's remains were found nearly seven weeks ago.
Billie Dunn's live-in boyfriend at the time of Hailey Dunn's late December 2010 disappearance – Shawn Adkins – has been the only named "person of interest" in the case.
Efforts to reach Adkins for comment in recent weeks have been unsuccessful.
Hailey Dunn's remains were found March 16 near the Scurry County lake. At that time, DPS, Texas Ranger and FBI investigators spent three and a half days at the crime scene to gather the teen's scattered remains and any evidence that could lead to a conviction. They were able to identify her through dental records.
Hailey Dunn was 13-years-old when her mother reported her missing on Dec. 28, 2010.
According to investigators, Adkins quit his job in Snyder the day of the teen's disappearance and is the last known person to have seen her.
According to Billie Dunn and Adkins, Hailey was on her way to a friend's house across the street from their home in the 1800 block of Chestnut Street when she went missing.
The pair failed polygraph tests when questioned about Hailey, according to an affidavit.
On two occasions, Adkins reportedly walked out of the polygraph examinations he volunteered for. He failed the first phase of his third exam and, during the second phase, indicated Hailey Dunn could be found in Scurry County but refused to complete the exam when more specific questions about her location were asked.
According to the affidavit, investigators used cell phone records to discover Adkins allegedly did not accurately portray his whereabouts the day of Hailey Dunn's whereabouts. Investigators said he visited Colorado City the day she went missing at a time she likely would have been home alone.
Investigators also said they discovered hundreds of articles about mass murderers in Adkins's and Billie Dunn's bedroom. Billie took responsibility for printing them out.
Six months after Hailey's disappearance, Billie Dunn moved to Austin.
Hailey Dunn's disappearance garnered national attention, including discussion on Nancy Grace.
