Investigators said the driver, Lionel Briscoe, 47, had his pants “unbuttoned and open to see his underwear.”

A woman was in the front passenger seat of Briscoe’s vehicle.

Briscoe told police he didn’t know the woman, but an officer recognized her as “a prostitute here in Fort Pierce.”

Asked why his pants were down, Briscoe told police he was “working out.”

A work out involving lowered trousers could not immediately be identified. Further, a review of summer and winter Olympic sports turned up no athletic event in which pants are in the down position.

Briscoe said he was going to take the woman to her home. He said he planned “to do something with her.”

Meanwhile, police asked the woman why Briscoe’s pants were down.

“What’s done is done,” she said.

In exchange for the intimate act, she said she was given a $20 bill.

Briscoe, of Port St. Lucie, was arrested on a misdemeanor sex offense and taken to jail.
