1. A Manifesto Purporting to Be From the Shooter Has Been Circulating on 8Chan

BREAKING: FBI investigating possible manifesto from the shooter which starts with the following two sentences: "In general, I support the Christchurch shooter and his manifesto. This attack is a response to the

Hispanic invasion of Texas" — Scott Stedman (@ScottMStedman) August 3, 2019

Reporter Scott Stedman has tweeted that he had told the FBI that a manifesto which was purported to be from the suspect had been circulating on 8Chan. Stedman said that the FBI is treating the manifesto seriously. 8Chan is a controversial message board that has been described as “the home of the most vitriolic content on the internet” by Vox.

That manifesto, which has been seen by Heavy.com but not verified as belonging to the suspect, makes negative references to Hispanic immigration into the U.S., criticizes both major political parties in the U.S. but the writer stresses that he supports some in the Republican Party in terms of immigration policies, the writer also makes reference to alleged Christchurch mosque shooter, Brenton Tarrant.

Heavy contacted El Paso Police and the FBI. El Paso Police confirmed there was only one person in custody. El Paso’s Mayor Dee Margo told the media that he was told that the shooting began in the parking lot of the mall. The suspect then entered the store.
