WILLIAMSTON, S.C. (AP) - Authorities say pesticide foggers may have killed a 10-month-old South Carolina boy and injured his 2-year-old brother.

Multiple media outlets reported that Anderson County Deputy Coroner Don McCown said the boys' mother had been using foggers to get rid of an insect problem.

He said investigators found seven fogger containers in the single-wide mobile home that are normally used to treat 6,000 square feet each.

Elizabeth Whitfield called 911 Sunday to report her youngest boy was having trouble breathing.

Paramedics took all three to a local hospital, where Jacob Whitfield died.

Kenneth Whitfield was flown to Greenville and remained in critical condition.

County fire officials say an unreported grease fire in the home did not appear connected to the baby's death.
