COLWYN BOROUGH is less than a mile wide, but its police department is in deep trouble after its acting chief was suspended Wednesday while officials investigate the possible coverup of an incident involving a juvenile who was Tasered while handcuffed in a holding cell. Deputy Chief Wendell Reed is the second officer to be suspended for the April 24 incident. The officer who allegedly administered the shock, Cpl. Trevor Parham, was suspended earlier this week, and a third officer who was there when it occurred is also expected to be suspended, according to sources and Colwyn Mayor Daniel Rutland.
