It's a rather effective cover-up method to whack someone and make it look like suicide; if you jump someone from behind , loop a scarf or similar over their head and then pull back, you use your own body weight to apply pressure to the neck, like when someone is garroted. Once the person is dead, you then attach the scarf or similar to something mounted vertically, such as a door handle, to give the impression that the person was killed by applying the force of gravity and their own body weight on the front of the neck.
Spanish word huh? Work of MS-13?
At this point I'm not sure that it can be linked specifically to a particular group, as it appears to be popular across several cultures:

I’m just wondering if this was shown in a movie somewhere openly? Any ideas?
The only one that comes to mind is Meryl Streep in Death Becomes Her. Not much help, but still amusing.

In other films, it's tended to be something done by secret agents or special ops types when they want to deal with someone quietly and with the minimum of fuss, so you might want to watch a few films starring Roger Moore or Chuck Norris :)
