When the wind carried several items out of Jeremy Gunter's boat -- and into Otter Creek Reservoir -- his 12-year-old son, jumped into the water to retrieve them.

Tragically, the boy was not wearing a life jacket, and the water was extremely cold.

When the boy got into trouble, Gunter jumped in after him -- also with no life jacket.

Authorities say the man succeeded in getting his son back to the boat -- but then disappeared under the water.

Search divers located his body several hours later.
