"It's amazing the tape exists. ... But to leave it in a house that's for sale -- where Realtors are going to be coming through it -- and leave it there for eight months -- is unbelievable," Young said.
Hunter said she left three videotapes and other items in storage at a Chatham County, N.C., house Young had rented for her, assuming they were safe.
In August 2008, she said, while living with the Youngs in Santa Barbara, Calif., she asked them to enter her former North Carolina residence to retrieve her passport, which was stored in the same box as her videotapes.
"I learned the video recordings were missing in September or October 2008, in conjunction with a move of my personal belongings," Hunter wrote. "I believe the Youngs or one of them in fact have possession of the video and/or one or more copies of the video."
Young said he made plans to secure the tapes to corroborate his side of the story -- if it came to that.
The allegations in Young's tell-all book have sent its subjects scrambling. It wasn't until last week, with the memoir about to be published, that Edwards abandoned his long denial, revealing that he was the father of Hunter's almost 2-year-old daughter.
Young's memoir has revealed details about the affair and the extent of the cover-up -- from Edwards' push for Hunter to abort, the scheme for Young to falsely claim paternity, to the nearly limitless funds from Edwards' wealthiest benefactors.
A federal grand jury in Raleigh, N.C. is investigating whether any crimes were committed in an effort to conceal Edwards' affair with Hunter.
