Those killed in Saturdays mass shooting at a Walmart in El Paso, Texas, apparently included a number of citizens of Mexico.

Mexican Foreign Minister Marcelo Ebrard tweeted on Monday that eight Mexican nationals were among the 22 people killed in the attack.

The 21-year-old man arrested for allegedly carrying out the attack is suspected of harboring racist and xenophobic beliefs. Authorities are investigating whether a four-page manifesto posted to the extremist online forum 8chan shortly before the shooting was written by the suspect, Patrick Crusius, a white man from a town near Dallas.

These are the names of the victims identified so far:

The 25-year-old mother of three was fatally shot while shielding her 2-month-old son in her arms, her sister told The Associated Press.
