Marshal's death clouds Vettel's Canadian Grand Prix victory
Death of marshal in track crane accident takes the shine off German world champion's maiden triumph in Canadian Grand Prix
Red Bull's triple world champion Sebastian Vettel won the Canadian Grand Prix, but his victory was overshadowed by the death of a marshal, the first fatality in Formula One in more than a decade.
The worker was killed after being run over by a mobile crane that was removing the Sauber of Esteban Gutierrez from the side of the track after he crashed in the closing stages.
Finally, we got our first win. It's off the list now and it was great to win.
Vettel, oblivious to the unfolding tragedy, captured his first Formula One victory on North American soil and extended his overall lead in the championship to 36 points over Ferrari's Fernando Alonso, who finished second.
Lewis Hamilton, who had won in Montreal three times before, was passed by Alonso seven laps from the end, but made it a podium of champions by finishing third for Mercedes.
Vettel, cruising to his 29th career win with little resistance, took the chequered flag 14.4 seconds clear of Spaniard Alonso.
"It was a great race and I had a great start, which was important," Vettel said. "Finally, we got our first win. It's off the list now and it was great to win."
Vettel's Australian teammate, Mark Webber, came fourth, and set the fastest lap, after his front wing was damaged when he collided with Dutch rookie Giedo van der Garde's Caterham.
