CINCINNATI (AP) — A man has been charged with aggravated murder in the aftermath of a slow-speed chase on Cincinnati-area interstate highways in which police say he held a handgun to his head. The suspect, Christopher McFerron, 44, initially faced charges including inducing panic after a chase that lasted more than an hour Saturday in the western Cincinnati area. Police said he ordered his wife out of the car on Interstate 74 and continued driving with a gun to his head, ingesting heroin before he was arrested.
