EVERETT, Wash. (AP) — Officials are sounding alarms after a baby died and two others apparently also overdosed in the past week in separate instances in which fentanyl was left unsecured inside residences, authorities said.

A 911 caller on Wednesday afternoon reported that a 13-month-old baby was not breathing in an apartment in Everett, the Daily Herald reported. The baby died later at a hospital, according to the Everett Fire Department. The Snohomish County Medical Examiner’s Office will determine the baby’s official cause and manner of death, officials said.

Last Saturday, firefighters were called to a residence after an 11-month-old was found unresponsive by the parents, a news release from the Everett fire and police departments said. The baby was given the opioid overdose reversal medication naloxone before firefighters arrived and provided further medical care, authorities said. The infant was then taken to a hospital and has since been released.
