A man accused of gunning down people at a busy Walmart in El Paso last month was indicted Thursday for capital murder. The District Attorney's Office issued a statement to CBS El Paso affiliate KDBC saying it "will continue to work hard to ensure that justice is done and is committed to assisting the victims through the judicial process."

Patrick Crusius, 21, of Allen, Texas, was indicted on one count in connection with the August 3 mass shooting that left 22 dead, District Attorney Jaime Esparza said. El Paso prosecutors are seeking the death penalty for Crusius, who remains jailed without bond.

The massacre was the first in a series of mass shootings last month that left dozens dead and, again, brought the debate over guns into the center of American politics.

Prosecutors have said Crusius surrendered to police after the attack saying, "I'm the shooter," and that he was targeting Mexicans. In court documents, prosecutors alleged that Crusius was the author of a racist screed published shortly before the shooting.

Federal prosecutors have said they are weighing hate-crime charges against Crusius that could also carry the death penalty.

Survivors of the El Paso attack have held vigils around the city, including outside of the jail in downtown El Paso where Crusius has been kept isolated from other prisoners, on suicide watch.

Less than 24 hours after the shooting in Texas, a masked gunman began shooting in a nightlife district of Dayton, Ohio, killing nine people and injuring 27 more. These shootings were followed weeks later by another in the West Texas cities of Midland and Odessa , where authorities say one man killed seven people and wounded about two dozen others while firing from a car. Unlike Crusius, the gunmen in both those attacks were killed by police.
