Where's the stain

Amateur, he must not know how to properly clean up.

Disgusts me to see people these days irresponsibly murdering, do it better, what are you an amateur. Fucking nomies

look at all that blood fucking amateurs not knowing how to do it with minimal evidence / how to clean up

Why does it look like a big pear?

The one stain looks like a dick.

Let mama deadpool show you how to clean up

That's real cute except drying blood turns brown rather quickly, black in large quantities. So unless the rest of the people in the room are all really calm about a murder that just took place this is a display/exhibit (.....obviously, .......I know it's funny). Still a little more realism wouldn't hurt and they didn't take into account how that blood would have gotten there. Arterial spray along with the falling of a body would seem to indicate a neck wound of someone really short standing beside the couch facing most likely to right side (our left). Not exactly a position good for an attacker. They would have had to reach over the back of the couch to strike.
