Texas Department of Public Safety Sgt. Erick Estrada told CNN's Anderson Cooper Tuesday there were two incidents involving the suspected gunman prior to the shooting at Robb Elementary School in Uvalde, Texas.
The first was the gunman shooting his grandmother, resulting in her being airlifted to a hospital, Estrada said.
The second incident was the suspect crashing a vehicle near the elementary school.
“The suspect did crash near a ditch nearby the school," Estrada said. "That’s where he exited his vehicle with what I believe was a rifle and that’s when he attempted to enter the school where he was engaged by law enforcement. Unfortunately, he was able to enter the premises and then from there that’s when he entered several classrooms and started shooting his firearm.”
Estrada went on to say the gunman was seen with a "long rifle and backpack."
Estrada could not confirm what type of rifle the gunman had, but says the Bureau of Alcohol, Tobacco, Firearms and Explosives is investigating.
On Wednesday, DPS spokesperson Lt. Chris Olivarez clarified information about what the shooter was wearing. Olivarez told CNN that gunman was wearing "a tactical vest carrier with no ballistic panels; so typically those type of carriers are used by tactical teams, SWAT teams, where they can place magazines, extra ammunition inside those carriers and be able to move in a tactical formation."
