New Development's In Case Of Missing Teen

There are new developments in the case of a missing Texas teen.  13-year-old Hailey Dunn has been missing since the end of December.  Hailey's mother's boyfriend, who is labeled a person of interest, admitted to investigators he threatened the lives of both the mother and daughter during a domestic dispute last year.

Below is an excerpt of what Hailey's mom said to a police dispatcher on February 14th of last year.

"I broke up with this guy a couple days ago and he's a little 'MHMR.' he's telling me that he's going to kill me and my ex-husband, and it's going to be remembered for a long time."

Court documents say the boyfriend originally told authorities he never threatened Hailey during the dispute, but then later admitted to threatening both of the Dunns.
