Go and find a weapon of some kind, like a fire extinguisher, then examine the lab coat guy.
Look both ways before crossing the road.
Before exiting into the hallway you check the other direction. Down the right side of the hall you can see a sharp turn leading in the direction behind you about forty feet away. Besides that you see a couple more blood smears on the wall, which get larger as they move leftward down the hall.
There is also a fire emergency box on the wall to the right. You decide that the coast is clear and exit the room. You open the fire emergency box hoping to find something to defend yourself with, and sure enough there is a bright red crowbar inside as well as a hose and "in case of emergency" lever. Though you're sure pulling the lever would do nothing.
You take the crowbar in hand and head off to check on the man in the lab coat. You notice that the left side of the hall ends in double doors about fifty feet from the room you exited, as well as doors every twenty feet or so staggered on both sides of the hall. (No door directly across the hall from another)
As you approach he takes notice of you,"H..he...help... help me," he stutters out as a small stream of blood begins to trickle down from his mouth to his chin.
You kneel down to examine his wounds. He puts one of his hands, shaking, on your left arm and attempts to mutter something but you can't quite tell what it is. Looking at his wounds, you find that he has been shot at least twice in the torso and once on the right side of his chest just under his collar bone.
You are no doctor but can tell that these wounds are fatal. He is already bleeding out and losing color in his face. The blood on his hands and chin are a stark contrast to his now almost porcelain skin. His breathing is fast and sporadic, with a slight wheezing or gurgling sound coming from his chest.
His hand grips your shoulder with what little strength he has. His blood shot eyes look faintly in your direction, though you think his vision may be fading as he isn't making eye contact, but merely looking at you.
You can think of no way to save this man's life so you decide to comfort him in his last moments. You lean in closer and hold him, wadding up his clothes around one of his wounds and applying pressure to make it seem like you are trying to save him.
With the other hand you hold his head against your chest as he weeps, gurgled words coming from his mouth,"Th.. thank... you..." Moments later his hand let's go of your shoulder and his head falls back. There was nothing you could do to save him and he clearly didn't have the ability to answer any questions you may have had for him.
What do you do next?
