The gunman in Tuesday's elementary school massacre was a lonely 18-year-old who was bullied over a childhood speech impediment, suffered from a fraught home life and lashed out violently against peers and strangers recently and over the years, friends and relatives said.
Using weapons purchased this month, days after his 18th birthday, authorities said, Salvador Rolando Ramos shot and critically wounded his grandmother. He then went on a shooting rampage at Robb Elementary School near his home in Uvalde, Texas, killing at least 19 children and two adults and injuring others.
Ramos also was fatally shot, apparently by police. The Texas Department of Public Safety said he was wearing body armor and armed with a rifle.
Santos Valdez Jr., 18, said he has known Ramos since early elementary school. They were friends, he said, until Ramos's behavior started to deteriorate.
They used to play video games like "Fortnite" and "Call of Duty." But then Ramos changed. Once, Valdez said, Ramos pulled up to a park where they often played basketball and had cuts all over his face. He first said a cat had scratched his face.
"Then he told me the truth, that he'd cut up his face with knives over and over and over," Valdez said. "I was like, 'You're crazy, bro, why would you do that?'"
Ramos said he did it for fun, Valdez recalled.
In middle school and junior high, Ramos was bullied for having a stutter and a strong lisp, friends and family said.
