She was on her way to an after-school event involving her 15-year-old daughter.
But the 41-year-old woman behind the wheel of her Mercedes never made it.
The driver was killed on the QEW at Third Line Thursday night, when a giant truck wheel suddenly snapped off a big rig, crossed the median and smashed through her windshield. It took only a few seconds and the victim had no time to react. She died instantly.
"Those tires, when they hit, it's almost like 1,000 pounds just coming down on you and it hits squarely in the vehicle right in the middle of the hood, the windshield and the roof," points out O.P.P. Cst. David Woodfield.
The trucker kept on driving for some 20 minutes after the accident, unaware it had even happened. The big rigs have three sets of tires and it's believed he wasn't even aware one was missing.
"He might feel a bump or a shudder maybe, but you know, you can feel that hitting big bumps in the road or potholes here and there," Woodward outlines. "So for him it may not have been unusual."
Police will be checking the truck's maintenance records but say this wasn't a case of loose wheelnuts. The tires came off together with the rims and brake drums attached.
"In order for it to come off, there's a hub assembly that's held on by wheel bearings, and there's nuts that will hold that wheel bearing and that hub assembly onto here," the veteran officer explains. "Something in that assembly has failed and that's why they've been able to come off."
Authorities don't expect to lay any criminal charges in the tragedy, but say the driver and/or the trucking company could face a fine up to $20,000 under the Highway Traffic Act.
The name of the victim hasn't been released.
