Authorities stated Wednesday that three employees of a funeral home in the border town of Reynosa confessed to releasing a video showing Valentin Elizalde’s autopsy. Elizalde, his manager and chauffeur were killed Nov. 25 after finishing a performance in Reynosa, Texas — across from the Texas town of McAllen. A minute-long video posted Friday on YouTube shows the body of musician Elizalde, filmed with a cell phone camera. His bloodied body lies on an autopsy table as his bloody clothes and boots are visible. In the background, people can be heard laughing.

According to Bolivar Hernandez, head of state police in Reynosa, funeral home employees Julio Martinez, Hector Lara and Nicolas Martinez admitted taking pictures and videos of Elizalde’s body. They have taken responsibility for this shameful act, Hernandez stated. Currently, authorities are trying to determine if the employees can be charged with a crime.

Elizalde closed his show at Reynosa’s annual fair with the song “A Mis Enemigos.” This song is used in a video posted on Youtube.com three months ago. The video features grisly images of people killed in drug-related violence overlaid onto a collage. It also features wanted posters of soldiers who allegedly joined the Gulf cartel— a top Mexican drug gang in Tamaulipas state. Lastly, it features footage of an alleged Gulf cartel hit man being shot in the head. Elizalde left this fair to return to his hometown of Reynosa, Texas, where he was subsequently killed by a gunmen hired by the Gulf cartel.

At the end of the video, images appear of Guzman, a Sinaloa mobster, cradling a baby while holding an automatic rifle.

Authorities aren’t sure if drug traffickers killed Elizalde to make a statement to the video creators, but they haven’t ruled it out.

Authorities say the $1 billion smuggling routes into the US controlled by the Sinaloa and Gulf cartels are fueling a wave of violence. Additionally, these cartels are fighting over control of border routes.
