Billie Dunn holds press conference

A woman said she spotted Hailey Dunn the night she disappeared, walking with a friend and a teenage boy, Dunn's mother said today in a news conference.Billie Dunn handed out a timeline (attached) to reporters, saying she had information that investigators had not previously revealed. According to that timeline, Hailey was seen at 8:30 p.m. on Dec. 27 with the friend whose house she said she was going to spend the night at. The witness didn't recognize the teenage boy who was with them.At last word, authorities stated Shawn Adkins, Billie Dunn's boyfriend, was the last person to see Hailey at 3:15 p.m. She told him she was going to stop by her dad's house, then to spend the night with her friend. According to earlier reports, she never showed up at either location. She was reported missing on Dec. 28.Billie Dunn was considered a "person of interest" in the investigation, but has been ruled out, said Pete Kampfer, spokesperson for the investigation.Dunn went on to say she was "very disappointed" with law enforcement for not naming other persons of interest in the case. Law enforcement has said they're looking at several persons of interest but have not named them. The only person they've identified as a suspect is Adkins.After saying that they hadn't spoke for some time, Billie Dunn now says she's in regular contact with Adkins. She described their current relationship as "friendly."Dunn also took issue with a few of the points released in police affidavits. She said the notion that she hosted a New Year's Eve party following Hailey's disappearance is ridiculous. Dunn also said she stopped at an ATM in Scurry County on the evening of December 27 because she was short on cash, not to buy illegal narcotics.See the video at
