CHARLOTTE COUNTY, Fla. - The Charlotte County Clerk's Office was shut down for a period of time Monday afternoon, following the discovery of a white powder substance.

It's believed that the powder was contained in an envelope that was sent by a jail inmate.

The Charlotte County Fire Department, EMS, HazMat crews were dispatched to the scene. HazMat crews processed the trunk of a deputy's car, as it's believed the letter may have been transported in that vehicle.
