The long-running criminal case against a Texas gunman who killed 23 people in a racist attack targeting Hispanic shoppers at a Walmart in El Paso in 2019 is on the verge of coming to a close.

What to know as the El Paso Walmart mass shooter is expected to make his final court appearance before spending the rest of his life in prison.

Patrick Crusius, 26, is already serving life in prison on federal charges, but his state case has been marred by delays.
