El Paso shooting fatalities now at 22 after victim dies at hospital Monday morning, police say

Two more victims of Saturday's mass shooting in El Paso died on Monday morning, raising the number of fatalities in the massacre to 22, officials said.

The mass shooting — one of the deadliest in modern U.S. history — unfolded at a Walmart around 11 a.m. Saturday, as 21-year-old suspect Patrick Crusius, allegedly opened fire in the store, initially killing at least 20 and injuring another 27.

Police and hospital officials announced that two additional people who were wounded in the attack died Monday. The number of those injured was initially 26, but at a news conference on Monday afternoon police said they increased that number to 27 because one person was self-admitted to the hospital and left on his own.

Police added that among those injured was an infant with broken bones. Thirteen U.S. citizens and seven Mexican nationals were among those killed, police told reporters on Monday afternoon.

Police said 15 patients are still in the hospital, two of which are listed in critical condition. They added nine of those injured have been discharged.

The Walmart was near capacity at the time of the shooting, with hundreds of shoppers inside along with 100 employees during the busy back-to-school shopping season.

Crusius was booked on capital murder charges. Authorities said Sunday the crimes he's accused of are being investigated as domestic terrorism. Officials were also looking into whether hate crime charges against Crusius are appropriate.

El Paso District Attorney Jaime Esparza said his office will seek the death penalty against the suspect.

"The loss of life is so great, we certainly have never seen this in our community. We are a very safe community," he told reporters at a news conference on Sunday. "We pride ourselves on the fact that we're so safe, and certainly this community is rocked, shocked and saddened by what has happened here yesterday."

Separately, hours later, a gunman wearing a mask, bulletproof vest, earplugs and carrying a rifle capable of holding at least 100 rounds also opened fire, outside a bar in Dayton, Ohio. At least nine people were killed and 27 others were wounded.

Some victims of the El Paso mass shooting have been identified. Among those killed was a 60-year-old man at the self-checkout line while his wife was in the bathroom, and a 15-year-old who was weeks away from starting 10th grade. A mother of three who was shielding her 2-month-old son from gunfire was fatally shot — her husband was, too.

El Paso Mayor Dee Margo said on "Fox News Sunday" the city's large Hispanic population played a part in why the community was targeted.

"We are the largest U.S. city on the Mexican border," he said. "Our region is a population inclusive of what is Mexico and southern New Mexico of two and a half million people. El Paso is 84 percent Hispanic to begin with."

Police said investigators were examining a manifesto that may have been written by the suspect and that indicated a “nexus to a hate crime," but further information was not immediately clear.

El Paso police Chief Greg Allen told reporters on Monday afternoon that the gun Crusius used was bought “near his hometown in Allen, Texas,”

“The weapon was purchased legally. It’s a 7.62 caliber weapon.”

When asked if the suspect was showing remorse, Allen said, “No, not to the investigators.”

He added, “He basically appears to be in the state of shock and confusion.”

“He took about 10 to 11 hours traveling from Allen, Texas to El Paso. As soon as he got here he was lost in a neighborhood,” Allen told reporters providing a timeline of what transpired before Crusius allegedly opened fire.

“After that he found his way to the Walmart because we understand he was hungry and that’s about as far as I can go without getting into too much detail.”

Allen told reporters Crusius had been cooperating with the investigation since the beginning.

"He volunteered most of the evidence that we're able to utilize at this time," Allen said.

Margo told reporters on Monday afternoon that President Trump called him on Sunday and offered to help in any way that he could. Margo said he is “already getting emails and phone calls” about welcoming Trump to town.

Democratic lawmakers and some residents have said Trump is not welcome in the largely Latino border city because of his past anti-immigrant rhetoric.

“I will ask President Trump to support our efforts with any and all federal resources that are available," Margo said. "Our recovery is no small task.”

He added, “I’m here to ensure that we receive every state and federal resource that is available to us that we need.”

The White House has not confirmed Trump’s schedule but the Federal Aviation Administration has advised pilots of a presidential visit that day to El Paso and Dayton, Ohio.

Crusius said in his application for a public defender, which was filed with the El Paso County district clerk’s office on Sunday, that he has been unemployed for five months and has been living with his grandparents.

Police shut down streets around Crusius’ grandparents’ home in the Dallas suburb of Allen in the hours after the mass shooting. The Federal Bureau of Investigation said agents searched their home and two others where Crusius had stayed.

In a statement, his grandparents said Crusius moved out of their home six weeks ago.
