A Florida couple has been charged with manslaughter after a family friend found their 8-month-old daughter dead from a fentanyl overdose earlier this month.

Investigators say that Nicholas Alexander put the baby in a playpen to sleep around midnight on May 31, WFLA reported. The little girl’s mother, Carissa Alexander, told detectives the girl was fussy and not sleeping, so she had been up with the baby between 1 a.m. and 7 a.m.

At about 10 a.m., the parents told investigators the baby was in a “prone position” on a couch cushion in the living room, although no one in the house could say who put her there.

The baby was not checked on until about 4:45 p.m., WWSB reported. At that time a family friend came by and noted that the baby was “ice cold.” The friend told the father, who began CPR while the friend called 911.

The friend drove the father and child to the hospital, according to the police report cited by WFLA, which said Alexander gave the baby Narcan because he thought she might have gotten into his “stash.”

A nurse at the hospital told detectives the child had been “gone for a while.”

“In my 17 years of experience, I’ve never seen anything like that,” the nurse said. “I have seen many deceased babies, but that’s the worse I’ve seen.”

Investigators wrote in their report that both of the Alexanders appeared impaired during interviews. They said they slurred their speech, couldn’t focus, and struggled to remain awake.

Nicholas Alexander said he “shot” cocaine at about 1 a.m. and smoked crack at about 10 a.m. His wife, he said, “took a hit” of the crack at that time as well.

An autopsy determined the baby had no signs of trauma and had been dead for several hours. A toxicology report said the child had lethal levels of fentanyl and benzoylecgonine in her system.

The Alexanders were both charged with aggravated manslaughter of a child and are being held without bond.
