Talk about a "pumping party" gone wrong. A woman has been charged with manslaughter after performing a penis-enlarging procedure that resulted in a man's death. Kasia Rivera, 34, injected silicone into the victim's penis at—of all places—her home in East Orange, N.J. Justin Street, 22, died of silicone embolism the day after the procedure, a medical examiner reported. Rivera was arrested for homicide and also charged with unauthorized practice of medicine. Police are continuing to investigate the case and asking other potential victims to come forward.
