In a disturbing case from Ohio, a 35-year-old woman stands accused of a heinous act against her own child. Tiffany Marie Lesueur allegedly attempted to poison her child by injecting human feces into the child’s IV port during a hospital stay earlier this month.

Authorities arrested Lesueur on Monday, charging her with child endangerment, according to documents reviewed by Law&Crime.

The alleged incident occurred at Nationwide Children’s Hospital in Columbus, situated roughly 140 miles southwest of Cleveland. Reports from local ABC and Fox affiliate WSYX indicated that the child was admitted on Friday, February 6, due to injuries believed to have resulted from abuse.

Details about the child, including their name, age, and gender, remain undisclosed.

On that same day, hospital personnel reportedly witnessed Lesueur using a syringe to administer an unknown substance into the child’s IV port, as per a report from Toledo ABC and CW affiliate WTVG. Following the incident, medical staff alerted the Columbus Police Department and noted that they would closely observe Lesueur’s interactions with her child during subsequent visits.

Two days later, while reviewing surveillance footage, hospital staff allegedly observed Lesueur making another attempt to contaminate her child’s IV.

The footage reportedly showed her go into the hospital bathroom carrying a specimen cup. When she exited the restroom, the cup appeared to be filled with fecal matter, WSYX reported. Lesueur allegedly proceeded to mix the fecal matter with a liquid before using a syringe to inject the mixture into the IV line attached to the child’s left hand.

Lesueur made her first appearance in Franklin County Court of Common Pleas on Tuesday where a judge reportedly ordered her to remain in detention on $250,000 bond. Should she post bond, Lesueur is prohibited from having any unsupervised contact with minors. She is currently scheduled to return to court for her preliminary hearing on Feb. 19.
