Indiana conservation officers are investigating the death of a man Wednesday that occurred around 7 p.m. on Little Chapman Lake. According to an Indiana Department of Natural Resources press release, officers responded to an unresponsive man in the water. Allegedly, the man was swimming near a boat with a female family member when she observed that the man had lost consciousness. She was unable to pull him back to the boat. Others on the lake assisted her into their boat but could not get the man out of the water. An off-duty Kosciusko County police officer arrived in his own boat and pulled the man out of the water. The officer began CPR and got the victim to shore. CPR was continued until EMS personnel arrived and took over. Despite efforts by those involved, the EMS were unable to resuscitate the victim. The Kosciusko County coroner pronounced him dead at the scene. According to Conservation Officer Jonathon Boyd, the name of the victim is being withheld until the next of kin, who are traveling outside the country, can be notified.
