Sounds like the elevator inside the head of Minnesota's Christie Prody has finally gotten to the top floor where O.J. Simpson is concerned.

In an two-part interview airing today and Wednesday at 5:30 p.m. on the CW, Prody tells "Inside Edition" senior correspondent Jim Moret, she believes Simpson killed his ex-wife, Nicole Brown Simpson, and her friend Ronald Goldman. Simpson was acquitted of the 1994 murders. He is currently serving time for armed robbery, after leading a raid in Nevada to reclaim memorabilia he said was stolen from him.

"A couple of years ago," Prody tells Moret, she started thinking Simpson committed the double murders of Brown Simpson and Goldman.

"Did he ever admit to you that he did it?" Moret asked. "In so many words, he did. I think he really had himself convinced that maybe he didn't do it," Prody tells Moret in a clip that was played for me over the phone by "Inside Edition" PR woman Irene Rogers.

Nearly 10 years ago, I met Prody at the Twin Cities home of her mother, Cathy Bellmore. Christie was a sullen young woman, who was very defensive about her romance with Simpson. Prody, who at that time bore a striking resemblance to Brown Simpson, was mildly miffed her mom had invited me over to vent her displeasure about her daughter's romance with Simpson.

Bellmore, with whom I lost contact when she moved away from the Twin Cities, in part to get away from being associated with her daughter's notorious boyfriend, has to be delighted by this development.

"Inside Edition" reports that Prody told Moret she was trapped for 13 years in a drug- and alcohol-fueled relationship with Simpson that was often violent.

Asked if she honestly believed Simpson would kill her if she left him, Prody said: "Yeah, I did... He called and said he would come there and shoot me and shoot himself."

When Simpson went to prison for the armed robbery -- he's appealing the conviction -- Prody went into rehab.

She is now engaged to marry the father of her new baby.
