At around midnight Monday night Richard Foster (25), Chris Foster (24), Laura Adams and Linda Adams entered Little Mouth Cave near Laconia, Indiana. After negotiating some crawlways they encountered a 40 foot pit. Richard "took a false step" and fell into the pit. In the fall he hit his forehead and sustained numerous bruises including a large scrape on his left thigh. After ten minutes he was able to rise and climb to a ledge halfway up. At that point Chris Foster tried to climb down to help but fell sustaining a head cut. Seeing that he was bleeding, the Adams sisters left to get help. Rescuers arrived in about an hour; one was able to negotiate the crawl and soon ascertained that Chris Foster was suffering from hypothermia. Ropes were brought through the crawls and the men were hauled up. They were able to walk away from the entrance with assistance.
The cavers, though supposedly experienced, had only flashlights, and no rope. They professed to only go into caves that they knew to be safe, yet when faced with an obviously dangerous situation they proceeded. Cavers looking for an accident.
Two cavers fell into a pit due to false steps and inadequate preparation, resulting in injuries and hypothermia.
