The alleged El Paso Walmart is believed to have written a disturbing manifesto filled with racism and hate, and apparently admitted he wanted to shoot as many Hispanics as he could, police said.

CNN reports that that manifesto, entitled “The Inconvenient Truth,” was posted on the online site “8chan” within minutes before 21-year-old Patrick Crusius opened fire into a crowd of shoppers. The majority of the writing centers around anti-Hispanic rants, including a “Hispanic invasion” and arguments against giving free healthcare and opening U.S. borders “to illegals.”

The writer of the manifesto also acknowledged that the public and media would blame President Trump for his actions, but claimed he had the same thoughts and views before Trump became president.

On Monday, Rep. Veronica Escobar, D-Texas, said during MSNBC’s “Morning Joe” show that one of the problems is that “Hispanic people have been dehumanized,” according to USA Today.

“This is one of the lowest points in American history, and if we don’t recognize this as such, we will not have the turning point that we so desperately need as a country.”

The manifesto also cited support for the New Zealand Christchurch shooter. In March, a shooter opened fire at two mosques, killing 51 people.

Local law enforcement indicated they believe Crusius is the author of the manifesto.

“From the manifesto that we first saw, we attribute that manifesto directly to him,” El Paso Police Chief Greg Allen said Sunday afternoon.

As CrimeOnline previously reported, Crusius has been arrested and charged with capital murder in connection with the Saturday morning mass shooting at the Walmart off of Hawkins and Gateway East boulevards. At least 22 were killed in the heartless massacre. Officials said many others are in area hospitals, in critical condition.

Authorities said during a Sunday press conference that the case is being treated as domestic terrorism and they’ll be seeking the death penalty. Allen added that Crusius readily admitted to the shootings after being detained.

“He was forthcoming with information. He basically didn’t hold anything back,” Allen said.

Two law enforcement officials told ABC News that the suspect admitted to investigators “he wanted to shoot as many Mexicans as possible.”

The outlet reports that the Walmart where the shootings took place is in an area where Mexican tourists frequently visit. Mexican President Andres Manuel Lopez Obrador indicated that three Mexican nationals were killed during the massacre.

However, according to Allen, the alleged shooter said he chose that particular Walmart after he had been driving for hours and became hungry.

“He took about 10 to 11 hours traveling from his home in Allen, Texas, to El Paso. As soon as he got here, he was lost in a neighborhood. After that, he found his way to the Walmart because we understand he was hungry. That’s about as far as I can go without getting into too much detail.’’

Investigators added that the shooter like cased the surroundings and ate before opening fire. He reportedly may have walked inside the store and looked around at the people before leaving to get his weapon, which has been described as an AK-47 style rifle.

He also put on safety glasses and earmuffs, officials said.
