A kilogram of fentanyl was stored on top of children's play mats used for napping at the New York City day care where a 1-year-old boy died from exposure to the drug, according to a new federal criminal complaint.
Three other children, ranging in age from 8 months to 2 years, were hospitalized and treated with Narcan and are now recovering, police said. An analysis of urine from one of the victims confirmed the presence of fentanyl, officials said.
