The Texas border city jolted by a weekend massacre at a Walmart absorbed more grief Monday as the death toll climbed to 22 and prepared for a visit from President Donald Trump over anger from El Paso residents and local Democratic leaders who say he isn't welcome and should stay away.
A makeshift memorial with candles and other items continues to grow in front of the scene.
The deaths on Monday raised the total to 22, El Paso police said on Twitter.
The shootings in Texas and OH were the 21st and 22nd mass killings of 2019 in the US, according to an AP/USA Today/Northeastern University mass murder database that tracks homicides where four or more people are killed - not including the offender.
Police are investigating a 2.300-word screed that Crusius allegedly posted to a forum, 8chan, some 20 minutes before the strike.
Separately, federal authorities will seek charges as it will be ruled as a case of domestic terrorism, which would also bear the death penalty.
Trump has frequently derided many asylum seekers and other immigrants coming across the USA southern border as liars and criminals.
Another patient remained in critical condition at the hospital, and five others were in stable condition, two days after the Saturday attack in which more than two dozen people were wounded.
Twenty-six people were injured, according to El Paso Police Chief Greg Allen.
The attack happened hours before a separate mass shooting in Dayton, Ohio, in which nine people were killed and others were wounded. El Paso has at least an 80% Hispanic population and constant comings and goings with its sister city Juarez immediately over the border in Mexico.
Police said the suspect opened fire with a rifle on shoppers, many of them bargain-hunting for back-to-school supplies, then surrendered to officers who confronted him outside the store.
KDFW-TV reported Crusius' grandparents issued a statement Sunday saying they were "devastated" by the rampage.
FBI investigators are conducting all their interviews in the Dallas-Fort Worth area and have not found any evidence that Crusius had connections in El Paso, special agent Jeanette Harper said at a press conference at 5 p.m. Sunday.
