TACOMA, Wash. — Investigators examined pieces of a drive train from an oversized truck Sunday to learn why parts tore off the truck and struck and killed a 6-year-old boy and injured another spectator at a monster truck show.
Witnesses described the boy, Sebastian Hizey, as being struck in the head by a Frisbee-sized chunk of metal that tore off a truck doing doughnuts during the Monster Jam show Friday night in the Tacoma Dome.
Police gathered loose parts of the drive train and the drive train loop, a special monster truck device that is supposed to hold the drive train on the vehicle, said Bill Easterling, senior operations director for Feld Motor Sports of Aurora, Ill.
He said he could give no further details or description of the loose parts, including where they were found.
"I've never seen the loop or the drive shaft parts come off like this," said Easterling, whose company is the promoter of the show.
Tacoma police Officer Mark Fulghum said no further information on the parts or other aspects of the investigation would be available before today at the earliest.
The second spectator struck by debris was taken to a hospital, but authorities haven't disclosed his name or condition.
Monster truck shows have been a staple at the Tacoma Dome for more than 20 years, featuring vehicles weighing 9,000 pounds or more and equipped with 5-foot tires. Drivers pop wheelies and engage in competition.
Feld has "a stellar safety record" with no prior significant accidents in Tacoma, said Mike Combs, city director of public assembly facilities.
The boy's father, Jessie Hizey of Puyallup, told the News Tribune of Tacoma that a metal ring weighing 7 to 12 pounds sheared off part his son's skull. They and other relatives were sitting in grandstands 20 to 25 feet above the arena floor.
Jessie Hizey said the red and silver truck, Natural High, at first failed to start and was hauled away by forklift. It returned to the show, and the metal ring flew from under the truck as it was spinning in tight circles in the mud.
"You go out for a night of fun, and you lose your son," Hizey said in a whisper, his face twisted in grief.
Easterly told the Seattle Post-Intelligencer the driver of Natural High was "absolutely devastated."
