Unexpected twist in Texas cold case murder probe: Victim was a bridesmaid in killer's wedding

For Texas Ranger Brandon Bess, almost everything about the Mary Catherine Edwards case was different.

Ranger Brandon Bess: The thing that really got me about the case was, you don't expect to have this beautiful, young, single, schoolteacher be murdered in her own home …. She was such a great person, came from such a great family.

Ranger Brandon Bess: It was an unusual crime scene. She's over the bathtub and she's obviously been sexually assaulted and handcuffed behind her back.
