Matthew proves to be deadly storm in Florida

TALLAHASSEE, Fla. (WOFL FOX 35) - Authorities say an elderly couple appears to have died from carbon monoxide poisoning while running a generator after Hurricane Matthew, raising the U.S. death toll from the storm to five.

A post on the St. Lucie County Fire District's Facebook page says rescuers responded to couple's home Friday morning after neighbors found them not breathing. They were taken to a nearby hospital, where county spokesman Erick Gill says they later died.  Officials say the couple had been running a generator inside their garage throughout the storm. Officials didn't immediately naming the couple.

At least three others in Florida were also killed in separate accidents.  

Earlier Friday, officials in St. Lucie were unable to tend a 58-year-old woman who had a heart attack during Hurricane Matthew, making her the first recorded fatality of the storm.

The Putnam County, Florida, Sheriff's Office reported Friday that a woman was killed and a man was injured near Crescent City when a tree fell on their camper during the storm.  A post on the sheriff's office Facebook page says the two adults were attempting to ride out the storm when high winds apparently caused the tree to fall. The man escaped with minor injuries, but the woman was killed.  Authorities didn't immediately name those victims.

Volusia County emergency management director Jim Judge reported the death of a 60-year-old woman after a tree fell on her house.  Judge says her family took her to a hospital, where she died.
