David Graves told the Canadian Broadcasting Corp. Ottawa police recovered the bodies of his 61-year-old wife Donna and 29-year-old son Daron Monday night.
They had disappeared Thursday night after telling him they were heading home after playing pool at the Prior Sports Bar and Restaurant in nearby Arnprior, Ontario.
They never made it and David Graves confirmed to the CBC their bodies were found in their vehicle, which had been spotted Saturday night in about 30 feet of water off a concrete pier at a ferry crossing. Icy conditions hampered efforts to remove the vehicle, which was brought to shore about 11:40 p.m. Monday.
Police considered the deaths traffic-related but were trying to determine why the vehicle wound up in the river.
