A pair of convicts can be found south of Primm, patrolling towards the Nevada Highway Patrol station. Oddly, they will not attack you on sight, but will instead warn you to back off unless you get too close.
The two convicts patrolling near the Nevada Highway Patrol station may end up fighting the Jackal raiders, who are waiting behind the building to ambush. Without intervention from The Player, the Jackals will usually kill the two criminals and hunt down the player next.
The convicts found in Primm are known for using dynamite in many instances. Killing them may be harder for lower-leveled players, as dynamite can be heavily damaging without proper prevention.
