New Jersey woman denies causing penis injection death

NEWARK, N.J. -- Authorities say a New Jersey man who died after having his penis injected with silicone was trying to get it enlarged.

The woman police say gave the injection, resulting in his death, has been charged with manslaughter. She made her first court appearance Tuesday.

The Essex County prosecutor's office says 34-year-old Kasia Rivera gave 22-year-old Justin Street the injection in May. She has pleaded not guilty but remains in jail on $75,000 bail.

Street died the day after his injection. His death was ruled a homicide following an investigation and a medical examiner's determination he died of a silicone embolism.

Rivera also faces charges accusing her of the unauthorized practice of medicine out of her East Orange apartment. Authorities say they're investigating whether she gave other people similar injections.
