OTTAWA -- Police have recovered a car and two bodies from the icy waters of the Ottawa River four days after a woman and her son went missing near the village of Fitzroy Harbour.

Police said early Tuesday morning they were finally able to get the Dodge Dart pulled from the river at 11:40 p.m. Monday night. A short time later, they recovered two bodies from the vehicle.

The deceased have not been positively identified, but they are believed to be Donna and Daron Graves.

The Graves left an Arnprior sports bar on Thursday but never made it home. The vehicle was found over the weekend at the site where the ferry docks, submerged in about eight to nine metres of water.

That set in motion efforts to recover the vehicle and the victims -- a task which was severely hampered by ice conditions on the river combined with current, blowing snow, strong winds and frigid cold air temperatures.

Dave Graves said Saturday he last heard from his wife and son when they called to say they were on their way home soon.

Police knew one body was in the vehicle shortly after finding it in the murky water, but could not tell if both victims were in the car until it was finally removed.

Police aren't saying exactly what happened, but the case is being handled by the collision investigation unit, which probes all serious and fatal crashes.
