Witnesses at the scene say the 2004 Ford F150 truck appeared to be about to leave a parking lot in Wakamow Valley, but then continued over the median and slowly drove into the lake. Foul play is not suspected.
The second occupant of the vehicle, a 45-year-old female, remains in hospital in critical condition. Her name will not be released at the request of her family.
