Kitty Wardwell was reported missing by her on-again, off again boyfriend, Frank Julian, back in July 1983 and was never seen again.
But after he died earlier this month, aged 80, relatives were clearing out his storage unit when they came across human remains in an unplugged freezer at a storage unit registered to him.
Maine Department of Public Safety spokesman Stephen McCausland told the Bangor Daily News: “Remains have been found, but we don’t know whose body this is definitively at this time.
“We have put both families in the loop about the discovery and we have interviewed a number of members of both families, but the final determination will be made by the medical examiner.”
He added: "Our investigation now looks to the Medical Examiner's Office for answers. DNA may need to be used to make a positive identification."
Wardwell was reported missing by a close pal, but when they questioned the novelty salesman at the time, he told cops that that he had dropped the then the then 29-year-old woman off at a Salem, NH, motel after a fight and had traveled back to his Lewiston ME home without her.
A later investigation revealed cops suspected she may have been the victim of foul play.
