Bjorn moves through the alleys towards the police station slowly, but with a clear purpose. He spots two walkers up ahead, both of them slowly ambling towards the police station. No need to draw even more attention than what has already been drawn by the gunfire. He slips his combat knife from it's sheath strapped to his leg and moves forward carefully, one of the walkers swings towards him as he reaches them. It is the first to truly die again as Bjorns knife plunges through its eye, he twists the knife savagely to ensure it destroys the brain. The second stumbles towards him as the first hits the ground. It is no luckier than the first. Bjorn kicks out, his combat booted foot connecting heavily with the walkers knee snapping the knee cap to the side. As the walker collapses under the weight of its own body Bjorn quickly moves in stabbing his knife right into the base of the walkers skull twisting it to destroy the brain stem.
He cleans his knife on one of the corpses rotting clothes before he slips it back into the sheath. His hands moving to once again bring up his slung UMP.45. He scans the area for threats, there was at least one other gunman in this place. Finding nothing he moves towards the police station, hiding behind a large metal dumpster he surveys the area. The walkers seem to be slowly ambling away, and it has been awhile since there was more gunfire. Either they are dead, or they came to their senses. He waits for a few moments longer until he spots a good opportunity to move. He slips into the police station, it has probably been picked clean already but it is worth a shot. If any place in town is likely to have .45 ammo it would be here, and if it was used as a base while it was all going down it may even have some tinned goods or MRE's.
Bjorn moves through the police station carefully, minding his foot placement. Right now he has no interest in finding the roof. He is only interested in the evidence lock up and the armory. Both may contain ammo and the evidence lock up may contain valuable bartering items such as drugs. His gun sweeps through the poorly lit police station as he moves, he has a good feeling about this place.
