Karen Johnson, 51, of Owatonna Minn. has been identified as the woman killed in a 1914 Ford Model T rollover at Zion National Park in Utah on Friday.
Investigators say the driver, a 19-year-old Owatonna man, pulled off state Route 9 to let faster traffic pass when the right front wheel's wooden spokes collapsed off pavement and the car overturned.
Brad Kubat's son was injured in what he told FOX 9 was a "total freak accident."
"Karen was just a phenomenal woman. Everybody that knew her was touched by her," Kubat said.
The incident occurred on the last day of an international Model T club's annual tour. Johnson was president of participating club, the T Totalers of Minnesota, an event that is said to draw participants together like family.
Three other individuals from Owatonna were left with non life-threatening injuries, Utah Highway Patrol Trooper Jalaine Hawkes said.
Hawkes says all four were ejected as the car wasn't equipped with seat belts and had its top down.
Model T experts say restraints are of little use in the soft-top vehicle that typically travels at no more than 30 mph.
