UVALDE, Texas — A gunman who killed 19 children and two teachers at a Texas elementary school in one of the deadliest school massacres in U.S. history barricaded himself inside a fourth-grade classroom, where all the fatalities and injuries occurred, state and federal officials said Wednesday.
“He was able to barricade himself inside the classroom,” Lt. Christopher Olivarez, a Texas Department of Public Safety spokesman, told the Los Angeles Times. “We’re still trying to confirm motive, what triggered him.”
The gunman opened fire in a single classroom, using a long rifle, possibly an AR-style gun, Olivarez said. Investigators are trying to determine where and how he obtained it.
