A capital murder charge was officially filed against the man accused of killing 22 people in a mass shooting at an East El Paso Walmart.

El Paso County District Attorney Jaime Esparza said that his office will seek the death penalty against Patrick Wood Crusius, 21, who was arrested in connection with the mass shooting at the El Paso Walmart.

Crusius was booked into the El Paso County Jail early Sunday morning on a charge of capital murder.

Crusius was arrested Saturday in connection with the eighth deadliest mass shooting in U.S. history.

He allegedly walked into a Walmart near Cielo Vista Mall at about 10:40 a.m. and fired a rifle at hundreds of customers and employees, according to El Paso Police Department officials.

The shooting left 22 people dead and 24 injured.

No bond has been set for Crusius, jail logs show.

Jail records list Crusius, who is from Allen, Texas, as being six feet tall, weighing about 220 pounds with brown eyes and hair.

Court records show that an attorney has been appointed for Crusius, although it does not state which El Paso lawyer was appointed to represent him.

Records do not show when or if a bond hearing will be held for Crusius.

El Paso shooting:

Crusius surrendered to police near the scene of the shooting.

El Paso Police Department and City of El Paso officials are expected to hold a news conference at 10 a.m. Sunday to provide further information on the shooting.

El Paso police officers, Texas Department of Public Safety troopers and other law enforcement officials were still at the scene of the Walmart, 7101 Gateway West Blvd., early Sunday morning.

Law enforcement is expected to remain at the scene throughout Sunday as they continue their investigation into the shooting.

El Paso police and initial reports Saturday morning said that the shooter opened fire at the Walmart and Cielo Vista Mall. Although, police said late Saturday night that the shooting took place only at the Walmart.
