On a lake in Indiana, a boat operator was driving a recreational motorboat with ten passengers aboard. The boat was alleged to have struck a large wave, causing the boat to tip and partially overturn on two occasions. Eight of the occupants, including the operator, were ejected from the boat on the first tipping event, and the remaining two occupants were ejected or jumped from the vessel during the second tipping. Surveillance video from a residence on the shoreline partially captured the tipping event. After the ejection of the occupants, the unmanned boat continued to circle clockwise. At some point after ejecting from the vessel, three occupants were struck by the boat and its propeller, and they sustained significant injuries. Some of the occupants of the boat reported that the incident occurred because it struck a "rogue" wave that was caused by a wake of another vessel being operated on the lake at the same time and approximate area.
