WARREN, Ohio - A Warren man pleaded not guilty on charges of child endangering in connection to the death of a three year-old.

Arthur Harper, 43, allegedly caused life-threatening injuries to Russell Catrell.

Harper is being held without bond at the Trumbull County Jail.

Catrell was in the care of his mother's live in boyfriend, Harper, Saturday night at their home on the 500 block of High Street.

Warren police say the child suffered severe head trauma after he was found unresponsive and not breathing.

He was taken to the Trumbull Memorial Hospital and transferred to Rainbow Babies Children's hospital in Cleveland, where he was later pronounced dead.

Police say the charges could change depending on the outcome of the investigation.

They are waiting on a Cuyahoga County coroner's report to determine the exact cause.
