Michael Hanlon Hinsperger, 57, disappeared from Carson Lake near Barry’s Bay, Ontario after a solo canoe trip on May 13, 2010. He was five feet tall and about 130 pounds. Michael and his wife Diane were on vacation at a cottage; she photographed him as he set out around 3 p.m. and he said he would be back for dinner, but he never returned.

The Ontario Provincial Police searched by air, with police dogs and dive teams. An overturned canoe was recovered on the lake, but there was no sign of Michael. After days of searching the water and shoreline the OPP called off the official effort. Michael’s family and friends continued to search the shores and nearby woods themselves and have maintained the missing person file.

What information might help fill the gaps about his route on the lake or the conditions that afternoon for those who were there that day?
