KANSAS CITY, Mo. (AP) — An Indiana woman whose husband and three children drowned when a duck boat sank in a Missouri lake has filed a federal lawsuit requesting an end to the manufacture and operation of the amphibious vehicles in the U.S. and elsewhere until they are redesigned for safety.

Tia Coleman, of Indianapolis, filed the lawsuit Tuesday against Ripley Entertainment and five other companies that manufacture and operate the Ride The Ducks tourist attraction.
