A Florida woman who posed as a physician confessed to administering silicone buttocks injections that caused a popular drag queen’s death.

Deanna Roberts, 47, pleaded guilty to eight felonies after injecting an illegal substance into four people, including Atlanta drag performer Lateasha Shuntel, the Atlanta U.S. attorney’s office announced on Monday.

The three other victims survived.

Shuntel, whose real name was Lateasha Hall, died in November 2015 after getting 10 injections into each of her buttocks. During the procedure, Roberts punctured one of her blood vessels, the Atlanta Constitution-Journal reported.

An autopsy revealed that the 45-year-old’s lungs were congested with the silicone, which also spread to her liver, kidney, heart, brain and spleen.

Roberts’ charges involved the possession, transportation and illegal injection of the silicone. Her sentencing is scheduled for May 24.
