“The media is infamous for fake news, their reaction to this attack will likely just confirm that - El Paso gunman’s bizarre post before shooting massacre

Authorities are examining a racist online manifesto allegedly posted on social media by the accused El Paso gunman who killed 20 people at a shopping centre in the United States.

The gun man also expressed support for the Christchurch massacre gunman.

Authorities are examining the document, in a bid to establish whether it was written by accused gunman Patrick Crusius.

I am simply defending my country from cultural and ethnic replacement brought on by an invasion, it states.

Twenty people are dead and 26 have been injured in the mass shooting at a Walmart store in El Paso, Texas, that has shocked and stunned the world.

The 21-year-old suspect, described as “a loner” and “a troubled youth”, was arrested without incident and is in custody.

The manifesto, titled The Inconvenient Truth, was posted by an anonymous user who posted another document under the file name “P. - Crusius.” That file was taken down, and it is not clear what it contained, according to AAP

A Twitter account that appeared to belong to Crusius was shut down on Saturday evening local time.

Tweets on the account had praised President Donald Trump and, in particular, his effort to build a wall along the US-Mexico border.

The manifesto begins by voicing support for the Christchurch mosque attack, in which Australian accused terrorist Brenton Tarrant allegedly shot dead 51 men, women and children in March, before declaring the El Paso attack to be “a response to the Hispanic invasion of Texas”.

It refers to the so-called Great Replacement — a white supremacist conspiracy theory that claims people of European descent are being overwhelmed.

Even if other non-immigrant targets would have a greater impact, I can’t bring myself to kill my fellow Americans, the manifesto states.

In short, America is rotting from the inside out, and peaceful means to stop this seem to be nearly impossible. The inconvenient truth is that our leaders, both Democrat AND Republican, have been failing us for decades.

It also said automation was people taking people’s jobs and that immigration should end.

I know that the media will probably call me a white supremacist anyway and blame Trump’s rhetoric, it said.

The media is infamous for fake news. Their reaction to this attack will likely just confirm that.

Authorities were investigating whether the massacre was a hate crime, after finding the manifesto believed to be written by the suspect online.

Authorities are looking at potentially bringing capital murder charges against him.

ALLEGED GUNMAN LIVED AT HOME WITH PARENTS, TWIN SISTER
Public records show Crusius’ last known address was his family’s home in Allen, Texas, about 30 minutes outside of Dallas and more than nine hours’ drive from El Paso.

He appeared to have lived with his parents twin sister Emily and their older brother.

After graduating from high school, Crusius attended Collin College in McKinney, Texas where he was still believed to be enrolled at the time of the massacre.

20-MINUTE SHOOTING RAMPAGE
Crusius allegedly went on a 20-minute shooting spree at the Walmart store, with one witness describing how “he went from aisle to aisle of the store, shooting with rage”.

Disturbing surveillance footage allegedly shows Crusius, who was wearing “miltary grade” earmuffs, walking through the front entrance of the Walmart store with an AK-47 assault rifle.

One law enforcement official told the Washington Examiner he “shot and killed locals that were fundraising outside the Walmart selling water. Children and adults”.
