You examine the blood.


Right away, you take into account that any living thing that lost this much blood would more than likely be dead, which makes the distinct lack of a body potentially concerning.

Inspecting the blood further, you find it has some odd properties. 
Its hue is a bit hard to pin down, as it almost seems to change as you look at it.
Additionally, you realize that you were only seeing the spots where it had previously pooled in significant amounts before, but there is more dried blood around in smaller quantities that is much more difficult to see:  It seems to have somewhat taken on the hue of its surroundings. 
The small amounts on the concrete are much more gray, while the drips on the chair turned black to match.

Following this, you are able to find a small trail of dried blood that leads out and away from the parking gate and into the nearby tunnel.

You check the utility knife, as well. You notice that the blood on its blade seems to be different from the rest you've found, and seems to be normal blood, as far as you are able to tell.

After examining it fully, you put the utility knife in the left pocket of your coat.
