Two suspects, Mendez and Brito, have been arrested and are facing federal charges of conspiracy to distribute narcotics resulting in death in connection to the death of 1-year-old Nicholas Dominici at a day care facility in New York City. Police found a kilogram of fentanyl in the day care, enough to kill 500,000 people, and it is unclear how the child was exposed to it. The investigation is ongoing and the suspects are due to appear in court later this week.
