The Monroe County Sheriff's Office said the U.S. Postal Service received a tip about a suspicious 10-pound package and it was given to Veronica Denise Johnson, 49, of Marathon, Fla., to deliver.
Deputies said Johnson took mail to the address on the package but placed the parcel itself in the trunk of her car.
Investigators said Johnson admitted she had been delivering packages of marijuana for a man who paid her $200 per delivery. She told deputies she had performed the service several times in the past and knew what was inside the packages.
Johnson was arrested and charged with possession of a felony amount of marijuana.
