A 27-year-old Bronx woman is dead after an unlicensed practitioner injected her with a trendy "anti-aging" solution at a wellness clinic — and the city Medical Examiner just ruled it a homicide. Elizabeth Baron's death is the price of a regulatory vacuum where anybody with a website and some vials can call themselves a holistic healer while the FDA looks the other way.

Baron went into cardiac arrest on July 19 moments after Luis Rojas Cabrera, founder of the Bereshit Lifestyle Center on Riverdale Avenue, injected her right hand with NAD+ — nicotinamide adenine dinucleotide — marketed as an "anti-aging therapy solution," according to the autopsy results released Monday. The cause of death was cardiac air embolism caused by the procedure. Cabrera called an ambulance, but medics at NewYork-Presbyterian Allen Hospital couldn't revive her.

Cabrera, 55, was arrested and charged with reckless endangerment and unauthorized practice of a profession. He was released without bail and ordered to surrender his passport. Prosecutors said he told cops he made "a very big mistake." The Bronx DA's office says the investigation is ongoing and charges could be upgraded.

Cabrera is licensed as a surgeon in the Dominican Republic but not in the United States — a fact that didn't stop his clinic's website, still live more than a month after Baron's death, from describing him as "an active surgeon and Naturopath in the Dominican Republic and an alternative and holistic medicine [practitioner] in the United States." That phrasing — carefully avoiding the word "licensed" when it comes to American practice — is the kind of linguistic sleight-of-hand that flourishes when regulators don't bother looking.

His attorney, Donald Vogelman, argued Monday that the medical examiner's homicide ruling is legally meaningless to the case. "The legal definition of homicide is the taking of a person's life, regardless of the intent or circumstances surrounding the death. This means homicide is not necessarily a murder but might be caused by an accident," Vogelman told the Daily News. "If there was a homicide in this case, it's clearly an accident. My client, Mr. Cabrera, will be fully exonerated in court."

This wasn't Cabrera's first brush with authorities over medical supplies. He was arrested twice in November at Newark Liberty International Airport returning from the Dominican Republic — first for possession of a metal baton, and four days later for nearly 200 vials of prescription medications, 30 tablets, and 10 syringes of lidocaine. Both cases were downgraded and dismissed, the Daily News reported.

The NAD+ craze has been fueled by celebrity endorsements — the New York Post noted that models Kendall Jenner and Hailey Bieber have publicly promoted the treatment — but the question neither outlet asked is where the FDA has been while unlicensed operators inject unregulated substances into paying customers.

NAD+ is not an FDA-approved therapy for anti-aging. It occupies the same gray zone as countless supplements and "wellness" products: sold freely, injected freely, regulated barely. The agency that moves mountains to police speech on social media can't seem to find the time to crack down on back-alley clinics shooting unverified compounds into women's hands.

Bronx DA Darcel Clark's spokesman said Monday: "Any person who feels they may have been victimized by this defendant is encouraged to contact the Bronx District Attorney's office." Cabrera is due back in court October 8.

The clinic's website stays up. The industry stays unregulated. And Elizabeth Baron stays dead.
