The Florida state attorney's office is looking into the matter, the Boston Herald said.
Claudia Williams said in an affidavit that she was present at a Nov. 2, 2000, meeting in Williams' hospital room when he consented to being frozen after death. Williams' remains currently are frozen in an Arizona lab.
"I was present in my father's hospital room on Nov. 2, 2000, when he verbally indicated he wanted to be cryonically preserved in bio-stasis," Claudia Williams said in the affidavit.
But, Ohio attorney John Heer, working with family and friends wanting to cremate Williams' remains, said he had proof that the hospital meeting never took place and two of Williams' former aides said they stood round-the-clock vigils at the hospital and Claudia Williams was not there on Nov. 2.
