He told the dispatcher he was hearing voices.

The Cuyahoga County Medical Examiner did not release a cause of death.

He first sounds calm on the 911 call, and then tells the dispatcher he’s “shaken.”

He stops answering the dispatcher’s questions at that point.

Ponomarenko is in jail on a charge of aggravated murder.

He’s scheduled to appear in court on March 29.

Neighbors told FOX 8 they heard a commotion before police arrived on the street.

Parma police were at the home for several hours.

They brought out several pieces of evidence.
