BALTIMORE (AP) — A Georgia woman with no license to practice medicine has been sentenced for injecting customers’ buttocks with commercial silicone in hotel rooms and using glue and cotton balls to prevent the substance from leaking out.

Forty-seven-year-old Kimberly Smedley of Atlanta was sentenced to three years in prison Thursday in federal court in Baltimore. She was also ordered to pay a $25,000 fine and more than $8,000 in restitution.

According to her plea agreement, Smedley administered the injections in hotel rooms in several cities, using silicone intended to be used for metal or plastic lubrication, as an additive for paint and coatings, and as furniture or automotive polish. The customers, who wanted their buttocks enlarged, paid between $500 and $1,600 in cash for each session.
