NYPD Chief of Detectives Joseph Kenny said during a press conference on Monday night that fentanyl was found in all three children.

"They seemed to be demonstrating an exposure to an opioid," Kenny said. "Quick-thinking FDNY, EMS personnel administered Narcan to these three children and removed them to Montefiore Hospital. Unfortunately, the 1-year-old did not survive and died at the hospital.

"Medical testing came back on all three children. All three children had fentanyl in their systems," he added. 

"NYPD detectives later learned that an additional child, only 2 years old, had been removed from the same location at 12:15 that afternoon by his mother. This child also began to exhibit symptoms of opioid exposure," Kenny said. "The child was brought the Bronx Lebanon Hospital, where hospital staff quickly administered Narcan, saving that child's life."
