Sam Warrick

 is found somewhere around the wasteland in a random encounter. Alone and carrying a Sniper Rifle, Sam is always hostile to the player and can be killed without karma loss. He also drops a finger as any other evil character, used to collect bounty. It is impossible to converse with this NPC unless you confuse him using the Mesmetron.

While caravan guards do not attack him they do chase him. If you enslave him you are paid 250 caps for him at Paradise Falls.

As a random encounter he has been spotted at a number of locations (see Fallout 3 random encounters). In one case he even appeared suddenly in the back area of the town of Arefu (which cannot be accessed from behind, since it is situated on the edge of a broken down freeway) and stayed there forever.

Kill tips
From a distance he's pretty lethal especially when you encounter him in the early stages of the game (I encountered him on my way to the super duper mart) Hide behind a large object (putting the object between you and him) so he cant target you and let him walk up to you. wait untill he's within or close to striking range. Then use any (firearm) weapon and your V.A.T.S system to take him down. Dont bother with legs or arms or torso. Go for the head. The trick is that when he needs to reload and your close to him he won't reload. keep shooting him in the head and keep close to him. He'll start running away but won't reload unless he's gained some distance. if you stay close you should be able to get some pretty devestating shots on his head in V.A.T.S. and thus quickly dropping its health. keep running after him untill you have regained enhough AP points and start using the V.A.T.S again.

Bugs
