Once, Suzanne M. Jensen told investigators, she used an overturned trash can to scale a wall at the base, the Tampa Bay Times reported Monday.
Last month, Jensen, 50, was charged with four counts of trespassing at MacDill Air Force Base and with possessing a stolen military ID. She has not yet been arrested.
The base, south of downtown Tampa, also is the home for U.S. Special Operations Command.
The offenses with which the woman is charged date back to October, when a retired Air Force officer found Jensen aboard his boat at the MacDill marina. She had the boat's keys in her hand and at first claimed to be with the Pentagon. When the man tried to detain her, she jumped into the water and swam away.
She was later found at a base restaurant and cited for trespassing.
Jensen was again cited for entering the base without permission in November, December and January.
She was charged with two counts of federal trespass in North Carolina in 2007, court records indicate. Those charges were dismissed. Jensen pleaded guilty to illegally entering Fort Myer in Virginia in August.
