Cpl. Jamie Vacon of Chester RCMP says the three were related.
The 9 year old boy was airlifted to the QE-2 Hospital in Halifax while the woman and 13 year old boy were transported by ground ambulance to Halifax. Two people in the SUV were sent to South Shore Regional with undetermined injuries. Their conditions today aren't known. Cause of the crash hasn't been determined but roads in the area were slippery at the time.
