On Tuesday morning, an 18-year-old gunman, identified by officials as Salvador Rolando Ramos, entered the Robb Elementary School campus, barged into one of the classrooms, barricaded himself, and opened fire using his rifle, killing 19 kids and 2 teachers.

Investigation revealed that the alleged shooter purchased the weapons a couple of months ago from a local store.

Speaking about how the 18-year-old obtained his guns and ammunition, Steven McCraw, director of the Texas Department of Public Safety, said at a news conference, “On March 17, Ramos purchased a semiautomatic rifle at a local sporting goods store. On March 18, he purchased 375 rounds of ammunition for that rifle. On March 20, he purchased another semiautomatic rifle at this same local store.”

Meanwhile, an official told CNN that Ramos dropped a black bag full of ammunition before entering the school. 

“Inside that bag was actually more ammunition. He actually dropped that ammunition and ran inside the school where he barricaded himself inside one of the classrooms and unfortunately, that is where he started conducting his business of shooting innocent children, shooting the two innocent adults that were inside that classroom,” Sgt. Erick Estrada of the Texas Department of Public Safety (DPS) told CNN.

Ramos was inside the school premises for close to an hour before law enforcement forcibly entered the classroom and shot him, officials said. 

Meanwhile, US President Joe Biden said he will be travelling to Texas “in the coming days” to meet with the families of the deceased. 

“Jill and I will be traveling to Texas in the coming days to meet with the families, and let them know that we have a sense of their pain, and hopefully bring some little comfort to the community in shock and grief and in trauma,” Biden said at the White House on Wednesday.
