Videos of Nuevo Laredo Wal-Mart Violence
Up until recently, no images have been released documenting the violence that took a two-year-old boy's life.
The Mexican media is admittedly refusing to cover any acts of violence in Nuevo Laredo, but people in Mexico have resorted to using the internet to inform each other about the dangers they may face from day to day.
This is a video someone anonymously posted to YouTube today. It shows the chaos inside that Wal-Mart on Sunday night.
It's one in a series of three videos that have gone up.
In it you can hear the store manager using the intercom loudspeaker to address the public inside, saying one of the exits had been sealed off for their safety.
The person operating the camera then goes to the door mentioned and shows shattered glass on the floor and steel shutters sealing people in while a gunfight goes on outside.
Another video shows people outside the store deciding what course of action to take until they finally decide to leave the scene as quickly as possible.
