On July 2, 1966, three young women went to Indiana Dunes State Park for a day of sunbathing and swimming. Witnesses reported seeing them leave their belongings unattended around noon and enter the water together, but they were later seen boarding a boat with an unknown man. After some time, the women were seen returning to the beach, before getting on a second boat with three unknown males. Unfortunately, they were never seen again. Could there have been a deadly boating accident? An abduction? A botched abortion on the water? Theories have swarmed this case for decades and tragically we still don't know what happened to Renee Bruhl, Ann Miller and Patricia Blough.
