SCURRY COUNTY, Texas - Calling it "sensitive information," the FBI won't disclose how many tips investigators have received since the remains of Colorado City teen Hailey Dunn were identified as those found in March in Scurry County.
However, spokeswoman Katherine Gilkinson Chaumont acknowledged investigators continue to receive tips – and urged individuals, regardless of the amount of information they may have, to consider contacting authorities.
"Even if they think information they have is insignificant," Gilkinson Chaumont said Friday.
The FBI is asking "anyone with information about the disappearance of Hailey" to contact the Scurry County Sheriff's Office at 325-573-3551, the FBI Dallas Division at 972-559-5000 or submit a tip online at tips.fbi.gov.
"Callers may remain anonymous," Gilkinson Chaumont said.
Hailey Dunn's remains were found March 16 near Lake JB Thomas in Scurry County. They were identified by law enforcement as being her remains on April 26.
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.
According to the FBI website, Hailey Dunn was last seen wearing the blue sweat pants, along with a short-sleeved shirt and pink and white tennis shoes.
Meanwhile, Hailey Dunn's mother apparently 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.
When Hailey Dunn's remains were found March 16 near the Scurry County lake, the 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.
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.
