Their 12-year-old son died after contracting the rare amoeba while spending the Fourth of July swimming and boating on a lake.

My son was a very smart individual. If he had one warning, he would have thought swimming in the lake was a bad idea," the boy's father said.

A lawyer for the family of 12-year-old Jaysen Carr said he died on July 18 after contracting a deadly infectious amoeba while swimming in a reservoir.
