At least 18 students and 1 teacher dead in Texas elementary school shooting

At least 18 children and 1 teacher are dead, as well as a teacher and the suspected gunman after a Texas elementary school shooting, Gov. Greg Abbott said. A 10 year-old girl remains missing following Tuesday's massacre.

The suspect is 18-year-old Uvalde, Texas, resident Salvador Ramos, Abbott told reporters at a press conference. It is believed the suspect was killed by responding law enforcement.

Officers said Ramos acted alone in his alleged rampage at Uvalde Elementary School, which has students in 2nd through 4th grade.

The shooting occurred during Uvalde School District's last week in session before the summer break, authorities said.

Ramos was a student at Uvalde High School and killed his grandmother before the alleged rampage, the Uvalde County Sheriff’s Office told the National Review.

Sources originally reported that the shooter was in custody.

"Texans across the state are grieving for the victims of this senseless crime and for the community of Uvalde," Texas Republican Gov. Abbott wrote in a press release. He said he directed state law enforcement agencies to help local officials respond to the tragedy.

The border town of Uvalde has about 16,000 residents and is about an hour and a half drive from San Antonio, where several patients were transferred to University Health for treatment. 

All Uvalde school district activities are canceled, and a press conference will be held later this afternoon, the school stated.
