Sheriff's Duster (Fallout 3)

The Sheriff's Duster is worn by Lucas Simms, the Megaton Sheriff. It bears resemblance to a trench coat, adorned with a silver badge on the chest. The Regulator Duster is also very similar. The duster is part of a set found on the body of Lucas Simms, after he has died or been killed by the player character.

The easiest way to kill Lucas Simms without Karma damage is to tell Mr. Burke to leave Megaton and tell Simms he wanted to blow the bomb. Burke pulls a pistol on him and kills him.
