“She then said she really wanted to be with Carrie,” he says in an exclusive preview of the interview obtained by TMZ. “In those precise words, and within 15 minutes from that conversation she faded out, and within 30 minutes, she technically was gone.”

When asked if Reynolds willed herself to die, Fisher said, “I’m saying that my mother, if anybody, had somehow a way to do that, and I watched it happen in front of my face. I was on her bed with her, and I watched her leave and go to Carrie.”

Family members are said to be planning a joint funeral for the mother and daughter. The two will be buried side by side so that they may be together in perpetuity, ensuring that Reynolds’ last request is fulfilled.
