An Atlanta woman pleaded guilty Wednesday to illegally injecting silicone into the rear ends of women seeking more voluptuous backsides in hotel rooms from Washington to New York.

Kimberly D. Smedley, 45, made at least $200,000 before she was caught after she botched injections in the buttock and hips of an exotic dancer at an Inner Harbor hotel in Baltimore, according to a plea agreement reached with the Maryland U.S. attorney.

The dancer paid $1,000 for the injections performed on a hotel bed before ending up in the hospital because of the toxic effects of silicone, according to court documents.

Smedley used commercially available silicone, which is intended for metal or plastic lubrication or as an additive for paint and furniture polish. She used super glue and cotton balls “in an effort to prevent the silicon from leaking out,” according to the agreement signed by Smedley and her Atlanta-based attorney, Steven P. Berne.

In announcing the agreement Wednesday, U.S. Attorney Rod J. Rosenstein said Smedley had “endangered her customers’ lives by injecting them with commercial silicone, causing at least one victim to suffer lung damage from a substance not approved by the Food and Drug Administration.”

Smedley pleaded guilty to “conspiracy to introduce and deliver for introduction into interstate commerce an adulterated and misbranded device” and faces up to five years in prison and a $250,000 fine. Her sentencing is set for July 12.
