A babysitter in Florida faces serious charges after allegedly poisoning an 11-month-old boy with antifreeze.

Anna Marie Adamo is now facing allegations of aggravated child abuse, attempted murder, and deliberately poisoning food or water with harmful intent. These charges come as detailed in a probable cause affidavit filed in the case.

According to the affidavit, detectives launched an investigation in February when the infant was hospitalized with ethylene glycol poisoning, the toxic substance present in antifreeze.

The child’s mother recounted that she had left him at Adamo’s residence at approximately 9:30 a.m. on February 12. At that time, the boy was not yet mobile, unable to crawl or walk, and incapable of self-feeding. She noted that he appeared healthy and well upon drop-off, having breastfed him beforehand. She also provided Adamo with two 3.5-ounce bottles of breast milk and some solid food for the child.

She said she kept in touch with the babysitter by text throughout the day, and that Adamo texted at about 2:30 p.m. and said the child was tired and asking if she could put him down for a nap.

About an hour later, the child’s grandmother picked him up from the babysitter and brought him to her home, noting that he appeared more tired than usual and “fell asleep immediately.” She met up with the boy’s mother about two hours later and that he was still sleeping, appearing “lethargic, unalert, and not able to hold his head up.” She told the father “something isn’t right.”

On the way home, the boy began to vomit “a clear sticky, odd smelling vomit.” She called her husband, who directed her to an emergency room, where doctors initially suspected flu or pneumonia. The boy was transferred to a different hospital which was better equipped to handle those illnesses, but while there he had a “full cardiac arrest,” prompting staff to perform CPR for 10 minutes.

The boy was taken to Nicklaus Children’s Hospital in Miami in critical condition, where tests ruled out diseases. That’s when he tested positive for crystal oxilate, which comes only from a genetic condition or antifreeze poisoning. The boy tested negative for the genetic condition and remained in hospital for a week.

Investigators spoke with Adamo, who told them she’d given the boy a 1-ounce bottle at about 11 a.m., and not one of the two larger bottles his mother had left with her. She also told them that her husband did not come home for lunch even though security cameras showed that he did.

She further refused to speak with investigators without her husband’s presence, and he ended the interview when detectives confronted her with poisoning accusations from 2014. In those accusations, Adamo was again the babysitter when a child testied positive for high levels of ethylene glycol, although no criminal charges were ever filed in that case.

A warrant was issued for Adamo’s arrest on October 3, and she was taken into custody in Valdosta, Georgia, where she now lives. She was brought back to Florida on October 14 and given a $600,000 bond, court records show.
