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. He can also be found out the front of the Car Dealership sometimes.

Kill Tips
From a distance he's pretty lethal, especially when you encounter him in the early stages of the game. Hide behind a large object that blocks his view (so he can't target you) and let him walk up to you. Wait until he's within or close to striking range, then use any firearm and your V.A.T.S system to take him down. Don't bother with his legs, arms, or torso - go for the head. 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 devastating shots on his head in V.A.T.S. and thus quickly dropping his health. Keep running after him until you have regained enough AP points and start using V.A.T.S again.

If you aim at his sniper rifle in V.A.T.S. and knock it out of his hands, he runs away scared and tries to duck and hide behind something. You can then run him down and use a melee weapon or an unarmed weapon to finish him off.
