A former trooper of the year in the Maryland State Police aviation unit faces a second-degree assault charge stemming from a domestic dispute at his Frederick County home. The Frederick News-Post reports that 39-year-old John Preston was charged Tuesday after his wife Mindi Valuckas said he briefly choked her with his hands.
