Who is Grover Teale from Killing Floor and what is their importance?

Mayor Grover Teale walks with a cane and runs the town of Margrave with no regard for the law. From an old Georgia family, Grover Teale had ancestors in the railroad that owned much of Margrave in the earlier years. A statue of Caspar Teale, the first Teale to have arrived still graced the center of town, and a Teale had been Mayor since the town's inception. Grover Teale was a tall old man with silver hair who looks every bit like the jerk he is. About seventy-five-years-old, he is pushy, loud, and as corrupt as the Chief of Police Morrison that he replaces.
