They call her "The Duchess."
Oneal Morris, who cops say posed as a doctor, has just been arrested for injecting her patients with silicone to make their butts bigger.
She's also accused of pumping up behinds with Fix-A-Flat—the same product that's used to repair tires!
Morris, who has pled not guilty, allegedly even injected herself.
Now, cops are charging her with manslaughter, following the death of a 31-year-old Florida woman.
Shatarka Nuby can be seen in a YouTube video, showing off her backroom enhancements.
Detectives say she was shot up at least 10 times by "The Duchess"—not with Fix-A-Flat, but with a household silicone sealant bought at Home Depot.
Morris reportedly even dressed up as a doctor when she saw her patients, wearing scrubs and a stethoscope.
Emotions are running high among people who say they were victimized by "The Duchess."
A brawl broke out when a Telemundo talk show did a show about "The Duchess" and claimed that she held "pumping parties," where silicone was injected straight into peoples' buttocks—and even faces.
Earlier this year, INSIDE EDITION's I-Squad uncovered a shady, underground world of back-room butt procedures. We sent an undercover producer, posing as a customer, to a hotel outside Cleveland to meet with a woman who said she could give us the injections.
The woman assured our producer, "You have nothing to worry about."
She asked our producer to go to another location for the injections, where Investigative Correspondent Lisa Guerrero was waiting to confront her.
We also found that you can order a self-injection kit from—get this—buttinjectionkits.com. All we had to do was send a $600 cash order to a New Jersey address.
Inside the kit were some ordinary band-aids, a few alcohol swabs, and 30 giant syringes filled with a gooey substance they said was medical-grade silicone oil.
But a lab test commissioned by INSIDE EDITION found it was, in fact, a type of adhesive used in toothpaste, detergent, and other products. And it was far from sterile.
The website where we bought the home injection kit appears to no longer be in business.
