Dentist Matthew Scott Mower, 40, of Christiansburg, was convicted Monday of assault and battery and interfering with an attempt to make a 911 call, and was given a suspended jail sentence and ordered to pay $900 restitution to a man whose cell phone he broke during a May altercation. He also was banned from Christiansburg’s Cambria Crossing neighborhood for a year. Mower still faces an array of drug, gun and driving charges in Radford, stemming from a January wreck in which investigators said Mower was carrying pills, two pistols and brass knuckles.
