The mother of Amber Hilberling, who is in prison for pushing her husband out of a 25th-floor apartment near downtown Tulsa, told Dr. Phil that her daughter was "set up" by being secretly videotaped talking to a family member after the killing.

"I believe they set this up," Rhonda Whitlock told the TV host on Wednesday's episode, apparently referring to Tulsa police detectives. “I believe they knew who we were in the community. The news was already over the scene. They had already decided who the parents were, who she was.”

Hilberling herself will appear on Thursday's show with the host, Phillip "Phil" McGraw, who traveled to Oklahoma for a behind-bars interview.

Then 19 years old, Hilberling was seven months pregnant in 2011 when her husband, Josh, fell to his death from the landmark University Club Tower, known for its unique round construction. Amber described it as an accident that happened during a physical argument, but she was sentenced to 25 years for second-degree murder.

During Wednesday's episode, Dr. Phil showed video clips from an emotional conversation that Hilberling had with her grandmother inside a police interrogation room, where she was being videotaped apparently without her knowledge. The tapes were later used against Hilberling during the trial.
