Date: Feb. 20, 2008

Victim: Dustin Mullett

Location: Worthington, Iowa

Model: 2007 Toyota Tundra

Details: Dustin Mullett was driving down Iowa 136, when his Tundra accelerated, reaching speeds of up to 100 mph, before veering and smashing into a tree in Worthington, Iowa, according to a complaint filed by Mullett's wife with the National Highway Traffic Safety Administration.

No other vehicles were involved in the winter afternoon accident that killed Mullett, according to the Dubuque County Sheriff's Department records division.

Mullett's wife suspected the 2008 accident was caused by a vehicle defect potentially involving the car's all-weather floor mat, the complaint said.
