Tuesday, July 31st, 2018 — The families of four of the 17 people killed when a World War Two-style tourist “duck boat” sank on a Missouri lake during a storm this month have sued the tour operator, saying it recklessly allowed the vessel out in dangerous weather. On Sunday, relatives of Ervin Coleman, 76, and 2-year-old Maxwell Ly, his great-nephew, both of Indianapolis, sued tour operator Ripley Entertainment Inc, which operates under the name Ride the Ducks, and vessel manufacturer Amphibious Vehicle Manufacturing LLC, a Ripley unit, alleging they “recklessly risked the lives of its passengers for purely financial reasons.”
