EL PASO, Texas (AP) Federal and state authorities continue to investigate the mass shooting at an El Paso, Texas, Walmart that left 22 people dead and more than two dozen others injured.

Police said Sunday that all bodies have been removed from the store and its parking lot, and that the attack did not spread to other nearby shopping areas. Police Sgt. Robert Gomez says most of the victims were inside the store.

Twenty-one-year-old Patrick Wood Crusius of Allen, Texas, has been booked on capital murder charges and jailed without bond. KDFW-TV reports his grandparents issued a statement Sunday saying they were “devastated” by the rampage.

Allen is more than 600 miles (965 kilometers) from where Saturday’s rampage occurred. The FBI says the suspect didn’t have any contacts in El Paso.

Detectives are also trying to determine with a racist, anti-immigrant screed posted online shortly before Saturday’s shooting was written by Crusius.

A hospital official says another victim of the weekend mass shooting in El Paso, Texas, has died.

Dr. Stephen Flaherty, of the Del Sol Medical Center, says the patient was one of two victims of Saturday’s attack to die at the hospital on Monday. Police earlier announced the death of one of the patients.

The new deaths bring the death toll from the attack to 22. More than two dozen other people were wounded.

The attack happened hours before a separate mass shooting in Dayton, Ohio, in which nine people were killed and others were wounded.
