Christopher Whitaker, 44, was arrested for the kidnapping and aggravated murder of the teenager. He was taken into custody at 7:15 Thursday night on Mayfield Road in Mayfield Heights by members of the Cleveland Division of Police and the United States Marshals Service.

According to Cleveland police, Whitaker was identified as the suspect in this case through evidence discovered by the Cuyahoga County Medical Examiner’s Office Northeast Ohio Regional Forensic Laboratory. The FOX 8 I-Team reported DNA helped identify the suspect.
