The two deceased could not swim, so the driver told them to get on top of the car while she swam to get help at a nearby home.||When the driver returned from getting help, the car, along with the two, were gone.||Officers searched the area for hours Saturday. Around 4:20 p.m., the boy's body was found in the flood waters. The female's was found shortly after, around...

This area experienced the event's most intense winds, extensive tree damage along with multiple points of structural damage to homes. As the tornado progressed eastward, it caused damage to an airplane hangar. While passing over the airfield, the KBMG ASOS recorded a wind gust of 70 mph.

What happened
WTHR-13 reported that Indiana Conservation officers found the body of 26-year-old man around 7:30pm Sunday the 3rd while searching Monroe Lake with side scan sonar equipment. He was in about 15 feet of water near the area where he had been swimming from his boat.||An Indiana Department of Natural Resources spokesperson said the man was swimming off a pontoon he rented with three friends when he disappeared Friday evening as a thunderstorm with strong winds passed overhead.||Friends say the man was a good swimmer, which might have been why he went into the water without a life jacket. When a storm suddenly kicked up out on the lake though, it was too much for him.
