Addressing a press briefing on the mass shooting at Robb Elementary School in Uvalde, Texas Governor Greg Abbott on Wednesday, 25 May, said that the attack weapon used by the assailant was an AR-15 assault rifle.

He added that the gunman had shared that he was "going to shoot an elementary school" around 15 minutes before the massacre started, through private messages on Facebook, AFP reported.

Abbott said,

"The first post was to the point of, he said 'I'm going to shoot my grandmother'...The second post was 'I shot my grandmother.' The third post, maybe less than 15 minutes before arriving at the school, was 'I'm going to shoot an elementary school.'"

Following the announcements, social media giant Facebook rushed to indicate that the 'posts' were one-to-one text messages, which were tracked after the tragedy.

"We are closely cooperating with law enforcement in their ongoing investigation," Meta spokesperson Andy Stone stated, AFP quoted.
