GAINESVILLE, Fla. -

A woman was killed when a tree fell on her north Florida home in the middle of the night, according to officials.

The Alachua County Sheriff's Office said 42-year-old Dawn M. Ewing and her husband, 40-year-old Michael L. Braton, were in bed early Wednesday morning when an enormous oak tree crashed through their roof and crushed them. Ewing died, but rescuers managed to get Braton to a Gainesville hospital for emergency surgery.

The couple's three children were in the home, but they were not injured.

Officials believe strong winds caused the tree -- estimated to stand at least 50 feet and roughly 4 feet around -- to fall on the single-wide mobile home.

A neighbor told The Gainesville Sun that the family had only moved in a few weeks ago.
