Circumstances of Disappearance

Mary Frances Gregory was last seen leaving her home in Parry Sound, Ontario on February 15, 1978. She was headed to Palo Alto, California for a vacation at the time.

It is believed that Mary departed Ontario by car with a male acquaintance. The man claimed that he drove through Pennsylvania, New York, Ohio, Illinois, Colorado, Utah, Arizona, and Nevada during the trip. He informed authorities that he dropped Mary off at a bus station in Las Vegas, Nevada, approximately ten days after leaving Ontario (February 28, 1978).

Mary never arrived in California and has not been heard from since. She was carrying luggage at the time of her disappearance. The bags have never been recovered. Foul play is suspected.
