A fake nurse who fatally injected a woman’s buttocks with a deadly combination of toxic substances will spend the next 10 years in prison.

Oneal Ron Morris, 36, smiled in a Broward County (Florida) courtroom after he was sentenced to a decade in prison on Monday.

Morris, who is a transsexual, plead guilty to manslaughter and injecting several women with an illegal mixture of Fix-a-flat tire sealant, mineral oil, commercial grade silicone, and Super Glue.

He shuffled into court in shackles, and wearing loose-fitting prison issue pants with what appeared to be towels stuffed down his back.

One of the women, Shatarka Nuby, 31, died after suffering in agony for hours. She died at Tallahassee’s federal prison in 2012.

Nuby reportedly paid Morris $2,000 for the procedures between 2007 and 2010, according to CBS Miami.

Court documents show Nuby received as many as 10 injections in her buttocks.

Several of Morris’ former clients confronted him in court on Monday.

“You gave us your word that the products you was using was A-1 products. And come to find out they were not,” said one victim named Kisha Jones. “Maybe in the beginning, but greed really took over, because you was pocketing the money from every victim.”
