Rodrigo de Medeiros Siqueira, a 33-year-old med spa owner from Quincy, MA, has pleaded guilty to injecting clients with unapproved botulinum toxin, obtained from illegitimate sources outside the US. The injections, which took place at his business, Rodrigo Beauty Inc., resulted in numerous severe cases of botulism. The crimes occurred between August 2022 and May 2025, with Medeiros Siqueira falsely representing himself as a licensed medical professional and making false statements about the identity and source of the botulinum toxin products.
The victims were diagnosed with botulism, a rare and dangerous illness that can cause life-threatening symptoms, including blurred or double vision, drooping eyelids, slurred speech, and difficulty swallowing or breathing. Medeiros Siqueira’s actions put his clients’ lives at risk, and his guilty plea is a step towards justice for the victims.
Medeiros Siqueira was arrested and charged in October 2025, and his sentencing is scheduled for August 12, 2026. The case highlights the dangers of unapproved and unregulated medical procedures, and the importance of ensuring that medical professionals are properly licensed and trained.
The investigation and prosecution of Medeiros Siqueira’s crimes demonstrate the commitment of law enforcement agencies to protecting public health and safety. The FBI and DOJ worked together to bring Medeiros Siqueira to justice, and their efforts serve as a warning to others who would engage in similar criminal activities.
