Sam Warrick

 (also called Ken Rollins in some localized versions) 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 difficult to converse with this NPC unless you confuse him using the Mesmetron, but he will sometimes say "I can see you there" if you get close to him while he is pursuing someone else.

While caravan guards do not attack him they do chase him. But he will engage and attempt to destroy other enemies, such as raiders, super mutants, and radscorps (and is pretty good at it) in the area. If you enslave him you are paid 250 caps for him at Paradise Falls.

Random Encounters
As a random encounter he has been spotted at a number of locations (see Fallout 3 random encounters):


 * In several cases 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, not shooting at anyone anymore. He can also be found out the front of the Car Dealership sometimes.


 * In the PS3 version: guarding a herd of brahmine on the path from The temple of the Union towards the Lincoln memorial.


 * On a path under the Abandoned shack housing Keller family transcript 4.


 * North of Smith Casey's Garage.


 * On the road just south-west of the Grayditch/Marigold station, north of the Red Racer Factory.


 * In the Jury St. Station area.


 * Outside of megaton or the surrounding area


 * Outside of Corvage Factory


 * On the pathway leading to the bridge at Shalebridge


 * Outside the Yao Guai Tunnels


 * Outside main entrance to Scrapyard, shooting a fleeing wastelander with his Sniper Rifle


 * On the lip of the crater near Rockbreaker's Last Gas.


 * Also, there have been occurences of sightings around Arefu Settlement.

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.

Another option is using the mesmetron to confuse him, then making him give you his knife and sniper rifle. This way he is easily killed, because he will run away, as mentioned above. This means that the sniper rifle will still have CND, making it useable.

If you went for the Alien Blaster early in the game (it should be your first trip out of Megaton (for those who are power gaming or have energy weapons as their main)), it makes short work of him. The A3-21's Plasma Rifle which you get from the Replicated Man quest, which also should be done early in the game (again, if energy weapons are your main form of attack), will also kill him with one shot.

Bugs

 * It is possible that he does not notice you and attacks only if you activate him, that is, talk to him.
 * Staying close to him if he needs to reload will make him run to gain distance, but as long as you stay close he won't actually reload.
 * Sometimes he doesn't drop the Sniper Rifle.
 * If you attach a slave collar to him and later attempt to remove it, the game freezes (Xbox 360).
 * After fast traveling one editor discovered him against the wall of a bombed out building equipping and unequipping his rifle but never firing a shot despite a raider and a super mutant master fighting well within shooting range of him. Only after uncrouching did he start firing at the PC
 * If he's being attacked by a mob, he wont attack you.
