The father of two died in May, just one day after undergoing the procedure.
Kasia Rivera appeared here in Essex County court Tuesday to face manslaughter charges.
The parents of her alleged victim were there too, trying to warn others about the danger of underground cosmetic procedures like the one that killed their son.
900 "We need to do something to stop this, my son died of this," said China Street, the victim's mother.
China Street's eyes brimmed with tears as she remembered her son Justin.
Justin, a father of two young boys, died in May of a silicone embolism.
The fatal clot in his lungs happened less than two days after he received an illegal silicone injection in his penis.
"He was 22, people can mock him, but this woman and others need to be stopped," Street said.
34-year old Kasia Rivera appeared in court Tuesday to face charges of manslaughter and practicing medicine without a license.
She had no medical training, but she appears to have been trying to teach herself using these books that we found outside the apartment she was just evicted from.
Investigators believe Rivera gave Sweet the injection at her apartment in East Orange.
Police believe she may have seen other people there too because she was advertising in local bars.
Rivera's business cards said she could "enhance your beauty", leading investigators to believe she was promising not just to make men's genitals bigger, but to enhance women's lips, breasts and buttocks as well.
"A lot of times people are embarrassed to talk about this, but we are not looking to humiliate people but we need to know about this because there's a health risk," said William Niafsay, the Essex Co. Assistant Prosecutor.
Justin Sweet's heartbroken parents are hoping that going public with the story of his untimely death will stop others from seeking out illegal silicone injections.
"I don't want another parent to go through what we're going through, so we want other people to come forward to put a stop to it," said Kysung Mills, the victim's father.
These underground silicone injections have grown popular as a cheap alternative to plastic surgery.
Experts warn they are very dangerous and they say if you've had them and you experience fever or shortness of breath, you should see a doctor immediately.
