The Execution of Joaquin Gallegos
The video was recorded on May 13, 2011, by members of La Línea and is directed at the members of El Chapo Guzman (probably sinaloa cartel) at the time.
In the recording lasting approximately five minutes in the original clip, there is a message in the beginning as "El Diego continues at 100 with La Linea. This is what is going to happen to the betrayals that do not believe and who support El Chapo" it says.
A man is inside a room wearing only underwear with his hands and feet tied, and blindfolded. Soon after two men begin to take action, the man rolls in pain and agony, because he can't do anything to defend himself.
Video is cut at 2:16 as it gets nasty after that.
