dunno, 3 minutes of stabbing?
no, lvl 2-mansion on first floor on left side
skill issue

Bro not a skill issue if I was intentionally headshotting them with the pistol / smg to test if it is possible to kill them. Which it is basically not.
Also shooting one in the head 3 times with the shotgun isn't a skill issue when crit chance is RNG. The point is even when you do a ton of damage to them they aren't going to die from getting knifed.
I am pretty sure the ones in the training arena where you shoot targets for score / money stuff have more health than the ones in regular mission.
If it is really as easy to do as you say, then please upload a recording of you doing so in level 10.
Edit:
Took 45 stabs when I landed a couple of headshots and stomps on one. After killing 5 of them with just non stop stabs to the belly / back, it is safe to say it took 60 stabs consistently.
I am in the process of testing if they regen health health or not.
Yes they do have health regen if you don't attack them for a while. That or they gain health regen when near each other.
The green one on the right on in the first screenshot, I stabbed him 43 times. Then stopped to stabbed the one with the black tanktop. The one in the black actually bugged out and took over 400 stabbings and was still alive. Which was about 10 minutes of non stop stabbing. I could see the blood splatter and stab marks whenever stabbed. I ended putting him out of his misery with 2 shotgun blast to the head.
I then went back to stab the green one. If he died after 27 additional stabs then it would of been safe to conclude that they don't have health regen. I had to stab him another 60 times for him to die. So it safe to conclude they do have health regen, but not sure exactly triggers it.
Side note it took 20 non headshot stabs to the back to kill a regular zombie.
