Two survivors have been discharged from a Missouri hospital after 17 people drowned when a “duck boat” sank during a storm. Reuters reports it was one of the deadliest U.S. tourist tragedies for years. Nine of the seventeen victims all belonged to the same family. The dead were aged one to 70 and came from six U.S. states. Seven of the 14 survivors were injured and taken to the hospital, authorities said.
