According to the criminal complaint, Tavarez worked at HCMC as a finance counselor and, as part of her job, collected co-payments from patients and entered them into the medical center’s billing system. When patients paid in cash, she would allegedly keep it and use the cash for herself. She would then void the cash payment in the HCMC’s billing system and would then charge another patient’s credit card to cover the theft.
