ROCHESTER -- A 3-year-old boy died on Thanksgiving Day, nine days after his father's car swerved off a country road and sank in a backyard pond.

Dylan Dusinberre was found floating in the 12-foot-deep pond shortly after the Nov. 18 crash in the town of Manchester in rural western New York and was placed on a ventilator. He died early Thursday at a hospital in Rochester.

Sean Dusinberre, a 37-year-old technician, drowned after kicking out the driver's side window and carrying Dylan to the surface on his back. His other son, 13-year-old Joshua, survived without injuries.

Dusinberre was driving his sons to Rochester when the car skidded on the season's first snowfall, veered off the two-lane highway and rolled down an embankment into the manmade pond, authorities said.

The car was traveling at around 50 mph on a road with a 55 mph speed limit, they said. Its speed on a slushy, snow-covered road and its inadequate rear tires were cited as factors contributing to the accident.
