S.T.A.L.K.E.R. SoC : Killing The Doctor

I have been playing Stalker Shadow of Chernobyl with the Complete mod. I had a lot of problems with the bloodsuckers so I made a save during Marked one's knockout. I died and I loaded the save. I noticed I had my binoculars equipped, so I changed to the Spas-12 and it worked. I killed the doctor and I got a anti-rad and bandage. This is the closest recreation of that I have. Also, I would recommend using a shotgun with shot rounds to be sure to kill him. If you haven't killed him with that use a grenade.

Can anyone tell me whether doc appears again in SoC? This glitch probably doesn't change the storyline because his corpse and his actor model are different. Also, this is only for the patient. You have to wait 1 minute for his actor to finish talking. If anyone wants the save:
