A couple who had been living in a trailer behind a home in Beloit is in jail, accused of allowing their one-and-half-year-old daughter to overdose on the powerful opiate fentanyl.

Smith Township police say 32-year-old Corey Douglas and 26-year-old Elizabeth Warner brought the toddler to the police department early Thursday claiming the child may have taken a Percocet while at the couple’s recreational vehicle on Johnson Road.

According to the police report, the girl’s lips were turning blue, she had a faint pulse and shallow breathing.

A police officer administered rescue breaths and gave the child a dose of the opiate overdose reversal drug, Narcan.

A rescue squad took the child to a hospital in Alliance.  She was later transferred to Akron Children’s Hospital where a social work reported seeing white powder on the toddler’s lips and hands.

Police say a toxicology report indicated fentanyl in the child’s system.

Douglas and Warner were arrested on charges of child endangering and booked into the Mahoning County jail.

An arraignment for the two is scheduled in Mahoning County Court in Sebring on Thursday.
