CLEVELAND — A judge in northeast Ohio sentenced a woman to life in prison without the possibility of parole Monday for the fatal stabbing of a 3-year-old boy as he sat in a grocery cart outside a supermarket.

Bionca Ellis, 34, of Cleveland, sat expressionless as Cuyahoga County Common Pleas Judge John Russo imposed the sentence for the June 2024 attack that killed 3-year-old Julian Wood and injured his mother, Margot Wood.

A jury found Ellis guilty earlier in October of aggravated murder, felonious assault, child endangering and aggravated theft. She has been held in jail on a $5 million bond since being indicted by a grand jury last year.

“I have seen unimaginable acts of violence — but this is among the most heartbreaking,” prosecutor Michael C. O’Malley said in a statement. “Bionca Ellis’ horrific actions warrant nothing less than life without parole.”

A message seeking comment was left for Ellis’ attorney, Fernando Mack.

Authorities said Ellis entered the Giant Eagle grocery store in North Olmsted armed with two knives that she had stolen from the Volunteers of America Thrift Store next door. They said she spotted Julian and his mother near the front and followed them into the parking lot.

The mother was about to load her groceries into her vehicle when Ellis ran at them with a knife, stabbing the toddler twice before walking away. The boy died at a hospital while Margot Wood was treated for a shoulder stab wound. Prosecutors said she tried to pull her son out of the cart during the attack.

Ellis’ defense attorneys had entered a plea of not guilty by reason of insanity.
