ABILENE, Texas - Hailey Dunn's mother hasn't been questioned by law enforcement since the Colorado City teen's remains were found in March near Lake JB Thomas in Scurry County, her attorney said Tuesday.
"Absolutely has not," said John Young, who is representing Billie Jean Dunn as local, state and federal investigators continue to investigate the death.
Young said Internet and other reports surfacing to the contrary are "patently false and inaccurate."
Billie Dunn's live-in boyfriend at the time of the middle school cheerleader's late December 2010 disappearance – Shawn Adkins – has been the only named "person of interest" in the case.
However, Young said, "I do not know what's happening with Shawn," noting Billie Dunn hasn't had any contact with him "in months."
Young said the only contact law enforcement has had with Billie Dunn since her daughter's remains were found "has been for the purposes of updating her on the status of lab tests and DNA tests to determine the identity of the remains."
Efforts to reach Adkins for comment in recent weeks have been unsuccessful.
"It's tragic. It's sad. It's a circumstance we all don't want to have to live through," Young said.
Meanwhile, Young said law enforcement still hasn't released Hailey Dunn's remains to her parents and that he hasn't been told when he should expect them to be released.
Young said he understands Billie Dunn has had contact with Hailey Dunn's father, Clint, and that he expects them to reach agreement as to funeral arrangements.
According to Young, an open-to-the-public memorial service will likely be held to honor Hailey Dunn's life, as well as those who searched and prayed relentlessly for her after her disappearance.
On April 26, local, state and federal officials confirmed the remains found at Lake JB Thomas were those of the previously missing Colorado City teen.
Attending a news conference in Scurry County were representatives of the Scurry County Sheriff's Office, the Texas Department of Public Safety, the Texas Rangers and the FBI.
At that time, officials said the investigation into the teen's death is ongoing.
In mid-March, 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.
