Parma Police responded to the home and apprehended Ponomarenko in the front yard, the prosecutor's office said. Authorities found the 5-year-old boy in the living room with blunt force injuries to his head and face. He was pronounced dead at the scene.
Cuyahoga County Prosecutor Michael O'Malley said in a statement, "Matthew Ponomarenko brutally beat and killed his own son. With this sentence, I hope that the family can find a modicum of peace and solace. May Jax's memory forever live in their hearts."
