The District Attorneys Office in Sweetwater has received a copy of a letter from a woman who was in jail at the time, but claims she witnessed a girl matching Hailey Dunn's description, being held captive in an Odessa house back in January of 2011.
The woman, identified as Sonja Renee Callahan, claims the girl was being held by kidnappers where she was drugged and eventually died.

WEST TEXAS- A possible breakthrough may have occurred in the case of the Colorado City teen who disappeared in December of 2010. Abilene news stations,KTAB-TV and KRBC-TV,are reporting that authorities are looking into allegations written in a letter from a woman, who was in jail at the time, but who claims she witnessed a girl matching Hailey Dunn's description, being held captive in an Odessa house.
Sonja Renee Callahan claims the girl was being held by kidnappers in an Odessa home where she was drugged and eventually died of an accidental overdose. The news agencies report the letter claims her body was then dumped behind the Ector County Coliseum. The letter she wrote was reportedly mailed out approximately four months ago.
The stations are also reporting that the FBI is investigating "persons of interest" based off information provided to authorities in the letter.
NewsWest 9 cannot confirm any of the information at this time. We have talked to the FBI in Midland, who claims to not know anything about this reported information.
Callahan, who was being held on drug charges in a facility in Odessa, reportedly sent the letter from the holding facility, to her own family members in Abilene. Those family members apparently shared the letter with investigators who told those news agencies that some of the leads in that letter have proven to be valuable, while other details in it have not.
Hailey Dunn would be 15 years-old now.
