Police said a faulty exhaust system was found on the vehicle where three people were found dead in northern Alberta earlier this month.
The mechanical inspection lead police to believe that exhaust may have leaked into the vehicle’s cabin.
The Jan. 22 release from Wood Buffalo RCMP didn’t say anything about cause of death, but the family of one of the three victims told Global News earlier this month, that the medical examiner said the cause of death was carbon monoxide poisoning.
Tanisha Peterson, 22, has been identified as one of three young adults found dead in a vehicle near Conklin, Alta. on Tuesday afternoon. Peterson’s mother told Global News the medical examiner told her the cause of her daughter’s death was carbon-monoxide poisoning.
Shortly before 12:30 p.m. on Jan. 9, police were called to the Laguna Access Road where a vehicle was stopped on the road.
The 29-year-old man in the driver’s seat was unresponsive, as were two passengers in the vehicle, a 21-year-old woman and a 22-year-old woman.

An inspection of the vehicle found a “faulty exhaust system component” may have caused exhaust to enter the idling vehicle.
An Edmonton mechanic suggests drivers routinely get their exhaust systems checked when swapping tires or getting an oil change.
Jim Johnston, owner of JimmyJ’s Custom Exhaust and Manufacturing, told Global News the exhaust flex pipe that comes off a vehicle’s engine can be damaged over time due to wear and tear.
“They do break. They create holes. Hard to hear. The fumes that come out of there are odourless, nobody knows,” he said. “It’s a simple, easy, quick check. Put your mind to rest, so you don’t have to worry about it.”
