A tree trimming service worker cutting trees in Charleston has died after being struck by a fallen branch that officials estimate weighed between 500 and 800 pounds.

Charleton Police Sgt. C.A. Dickinson says the victim, whose name hasn't been released, was part of a two-man crew working to remove a smaller tree Monday morning. When the smaller tree was moved, a weak branch on an adjacent larger tree fell about 40 feet, hitting the victim.

The accident occurred near Greenbrier Street and Hillcrest Drive.
