10-Month-Old Baby Dies After Ingesting Fentanyl While In Babysitter's Care; Accused Arrested

A 10-month-old baby in Florida died of "cardiac arrest" after ingesting fentanyl. Police have arrested the child's babysitter in connection with the death.

Wednesday's arrest was related to a March 31 incident. Palm Beach County deputies were called to the intersection of Military Trail and Boynton Beach Boulevard after a baby suffered a medical episode, NBC affiliate WPTV reported.

The baby girl was in the back seat of a 2016 Audi SUV driven by 32-year-old Kelly Kirwan, who was caring for the child.

Palm Beach County firefighters said the baby was "unconscious and unresponsive." The child was rushed to a hospital in Boyton Beach. Doctors said the infant "did not have any brain activity or nerve response" when she was brought to the hospital. A few days later, the child was declared dead.

During questioning, Kirwan told investigators that the baby was excessively fussy and inconsolable, which was why she made her a bottle of formula and laid her down to sleep. When the woman realized she was out of formula, she decided to go to a nearby Target store.

She put the baby in the car and drove to Target. The 10-month-old "seemed excessively drowsy" and was "slumping her head forward," the woman claimed.

In the car, Kirwan reportedly made a video call to a man who noticed the child was making "strange noises while slumped over." He asked Kirwan to call 911, NBC Miami reported.

When Palm Beach County detectives searched Kirwan's apartment, they found "Benadryl pills on the couch, several prescription pill bottles throughout the apartment, a bar containing bottles of alcohol," along with "an empty capsule of suspected drugs inside the bedroom."

A baby pacifier and a pump nasal spray were found on the bed near the empty capsule. Forensic and chemical tests showed the empty capsule had a "tentative positive result" for fentanyl and parafluorofentanyl.

"It is known to law enforcement that empty capsules may contain narcotic and, or illegal substances such as fentanyl," the arrest report said.

A judge set Kirwan's bond at $300,000 and ordered her to have no contact with witnesses in the case or children under the age of 18.
