WILLIAMSTON, S.C. (AP) Authorities say bug spray that produces a fog to kill insects may be to blame for the death of a 10-month-old South Carolina boy and his critically injured 2-year-old brother.

Anderson County Deputy Coroner Don McCown said the boys' mother had been using foggers because of an insect problem. Elizabeth Whitfield called 911 on Sunday to report her youngest boy was having trouble breathing. Paramedics took all three to a hospital, where Jacob Whitfield died.

Kenneth Whitfield remained in critical condition, and Elizabeth Whitfield returned to the ER with breathing problems.

McCown says investigators found seven fogger containers in the single-wide mobile home. He says a single fogger is typically used to treat 6,000 cubic feet.
