At least 19 people have been killed and 26 others wounded in El Paso, Texas after a gunman armed with an AK-47 entered a shopping and began firing.

The gunman has been identified as 21-year-old Patrick Crusius. He has been taken into custody by law enforcement.

Investigators are looking into a manifesto allegedly posted online by Crusius days before the shooting. According to sources, the manifesto voiced anti-Hispanic sentiments and decried the immigrant “invasion” of El Paso.

Additionally, a Twitter account that likely belongs to the gunman has emerged. The account was created in 2016 and the last sign of activity on the account was in 2017. However, it shows more than one post that voiced support for President Trump.

In one post from January 2017, the user believed to be Crusius shared a survey which asked, “What is the best way to secure our country?”

With the survey, the user wrote, “#BuildTheWall is the best way that @POTUS has worked to secure our country so far.”

El Paso shooter clearly outlined his motives, political views, biography, and outlined his gear for the day of the attack on his computer.

Other posts on Crusius’ alleged Twitter account show an apparent hostility towards animal rights activists. In one reply to the “Mercy for Animals” official account, the user writes, “Ugh you hipsters don’t realize that it is God’s will for humans to do whatever they please with animals. Foolish people say otherwise!!!”

Initial reports said “multiple” suspects were taken into custody in the wake of the shooting, but police are now confirming that the possibility of more than one suspect has been “ruled out.”

Update, 4:51 pm PST:

The Twitter account mentioned in this article has since been suspended. Another Twitter profile allegedly belonging to Crusius has since been suspended as well, but screenshots sent to DeadState by a reader show the profile’s posts to be more current. The profile, which used the handle @PatrickCrusius and was created in July of 2019, had a cover image featuring Charleston shooter Dylan Roof. In the profile’s bio, the user describes himself as an “amateur ghost hunter,” a “proud God loving Christian,” and “anti-abortion.”

Other screenshots show multiple retweets of posts from former KKK Grand Wizard David Duke, along with a post that seemingly praised the recent mass shooting at a garlic festival in Gilroy, California.

One post mocked the late rapper Nipsey Hussle who was gunned down this March in Los Angeles.
