The step-mom of the murdered wife of an America's Got Talent contestant has revealed how a mysterious incident took place at a hotel ice machine in the middle of the night - just hours before the woman plunged to her death.

Speaking exclusively to RadarOnline.com, Elba Sutterlin said Laura Finley went to get ice from the hotel corridor around 3am. When she returned, the woman told husband Joe: "You won't believe what somebody tried to do to me when I went to get ice."

"Joe says he told Laura they would talk about it in the morning because he needed to get some sleep," Elba told RadarOnline.com, in an exclusive interview.

"When he woke up and Laura wasn't there, Joe thought she had gone to get him breakfast so he went to get in line thinking they would meet up."
