It's another one of those videos to get people talking. We've all seen the video of the scary girl that suddenly appears in an elevator after the power goes and comes back on, scaring the heck out of unsuspecting victims, well, lo' and behold, someone has created one around MURDER!

Here's the set up: Elevator door opens just as people try to enter, when they see a man being strangled. What would you do?!!

The reactions of the victims in the CNN video story are ones of shock, retreat, jumping in to help, and even one guy decides to record it on his phone.
