Is it possible to kill Mario?

In Party Hard, Mario will appear every now and then to board up a shortcut (such as the open window on the far right side on the screenshot below:

I've circled him in Yellow, you can see he is heading over there now.

I've tried stabbing him but it doesn't seem to work - he just turns around and kills me instead. I've also tried traps but he's either too quick for them or I am mis-timing the activation.

Is there any way to kill him and prevent the shortcuts from being closed?

It is not possible to kill the Mario that closes off shortcuts. He is immune to traps, bombs, and any other kind of damage. In the casino level I tried to electrocute him with the hanging wire on the stage, set the kitchen he was in on fire, have the oven blow up on him, hit him with the car, and out of desperation use the sword on him. All connected and all failed.

There is another Mario seen in the picture below that is the guest of the party most notable in the rooftop pool party level that is killable, however killing him does not stop the other Mario from showing up or make him killable.

From this discussion, people have stated that he can be killed via traps or by several environmental uses.

This is the only information I could find on the web regarding Mario on Party Hard; I hope this helps...
