The death of a woman who got butt enhancement injections is being ruled a homicide, police sources say.

Blanche Barnwell, 40, the director of health coordination at BOOM!Health, died August 4 in her Bronx apartment. The medical examiner's office determined her death was a homicide caused by "silicone injections in the buttocks," which caused an embolism.

It isn't clear whether Barnwell had the procedure done at home or somewhere else.
