Isaac Death Toll Rises to Four

Authorities say the bodies of a man and a woman have been found in a home in the flood-ravaged Louisiana community of Braithwaite.

Billy Nungesser, president of Louisiana's Plaquemines Parish, said deputies went out to search for the couple Thursday evening after someone reported the man and woman had apparently not escaped the flooding there after Hurricane Isaac pummeled the Gulf Coast.

Authorities said the discovery raises the death toll from Isaac to at least four in Louisiana and Mississippi.

Nungesser says the bodies have been sent to a coroner's office, where autopsies will be performed. Their names were not immediately released.

Dozens had been rescued from their homes after floodwaters swamped Braithwaite during Isaac's storm surge earlier this week.
