Salvador Ramos

The hour-long interval before border agents stormed in appeared to be at odds with an approach adopted by many law enforcement agencies.

Salvador Ramos shot and killed 19 children plus two teachers after shooting his grandmother at the house they shared.

Penahanan itu adalah sehari selepas 19 orang kanak-kanak ditembak mati di sebuah sekolah rendah di negeri itu, kata polis.

The gunman posted an online message warning that he was going to shoot up an elementary school minutes before he attacked, Greg said.

The carnage began with the 18-year-old suspect, identified as Salvador Ramos, shooting his own grandmother, who survived, authorities said.

Lelaki itu, yang tidak mahu dikenali, berkata dia agak "rapat" dengan Ramos dan pernah diajak bermain Xbox bersama-sama.

The 18-year-old suspect was apparently killed by police officers responding to the scene, Governor Greg said.

Angka kematian terkini insiden tembakan di Sekolah Rendah Robb dilapor meningkat kepada 21, 18 daripadanya murid sekolah tersebut.

Walau bagaimanapun, keadaan nenek suspek yang tidak dinamakan itu setakat ini masih belum diketahui.
