New York ? Sheriff’s officials investigating a tour boat capsizing last fall that killed 20 elderly passengers concluded in a report released Friday that neither the vessel’s owner nor its captain committed a crime.

The Warren County Sheriff’s Office looked into whether there was any intentional, reckless or negligent conduct that amounted to a crime, and submitted its findings to prosecutors. They are conducting their own investigation into the Oct. 2 accident in the Adirondacks and could still pursue a case.

Several victims and other witnesses said the 40-foot Ethan Allen appeared filled to capacity or beyond on a calm, sunny Sunday when it suddenly tipped over, sending screaming passengers into Lake George. Pleasure boaters threw life preservers to the victims and pulled people to safety, but others were trapped beneath the boat.
