As time has passed, the full magnitude of the shooting in and around an El Paso Walmart store has become more clear. After a 21-year-old Allen, Texas man opened fire with what is reported to be an AK-47 rifle, 20 people are dead and 26 have been injured.
From NBC News . . .
Multiple senior law enforcement officials believe Crusius posted a screed online just prior to the attack. They say investigators are examining a posting they suspect is from him but that they have not officially confirmed it.
The sources said it was too soon to draw any motives from the posting.
A second person was also taken into custody, but it was not immediately known what role, if any, the person played in the shooting, sources familiar with the investigation told NBC News.
More details will be revealed as the investigation progresses, but the first call to El Paso police was received at 10:39a this morning according to Gregory Allen, El Paso chief of police. He said that the first officer arrived on the scene at 10:45a.
Chief Allen said in a televised press conference that the shooter was arrested outside the store and surrendered without incident as soon as he was approached by police officers.
ATF and FBI are currently involved in the investigation along with local and state law enforcement.
