A good deed in the line of duty and Dallas loses an officer The deadly mix of alcohol, a motor vehicle and disregard for danger and consequences. Steve Martindale pays his respects to fallen Dallas Police officer Mitchell Penton at the DPD Northeast Patrol Division building on Saturday, Feb. 13, 2021, in Dallas. Officials say Penton was struck by an intoxicated driver around 1:45 a.m. on Saturday when Penton was working a crash scene in the northbound lanes of the North Central Expressway at Walnut Hill Lane.
