I'm sorry, Mate. If it was salt water, the camera is most likely done. If it was fresh water, there may be a chance. Some people suggest putting it in a air-tight bag with some desicant, those drying packets you can buy for your gear or find in packaging for dried food. The idea is to try to soak up the last bit of moisture in the camera. I flooded a point-and-shoot in a case just a little bit in the ocean. It was dead but when it dried out, it turned on. It was back from the dead not never quite the same, kinda like a zombie. I flooded a Nikon digital SLR in a housing, sent it to Nikon for repair, and they kinda laughed at me.
Sorry to hear about your loss but I hope you and your wife are back to shooting photos soon!
Cheers,
