A lawsuit filed against an amusement ride maker says the company knew years before about a defect that caused a deadly crash at the Ohio State Fair.
The family of an 18-year-old who died at the fair and three others who were seriously injured in 2017 filed the lawsuit Monday against Dutch manufacturer KMG.
Attorneys say they have a letter sent by the company in 2012 that shows it knew about a design flaw that could cause rusting.
KMG previously has said the cause was excessive corrosion of a support beam where a carriage on the Fire Ball ride broke apart and ejected two passengers.
The company did not respond to a call seeking comment on the lawsuit.
