SUTHERLAND SPRINGS, Tex. — As he shot and shot between the pews, the gunman who killed 26 people in a Texas church last Sunday also shouted. Joaquín Ramírez, whose girlfriend was hit by one of Devin P. Kelley’s bullets, cannot shake his awful words.

“You’re gonna die,” Mr. Kelley said in a fury, before screaming out a curse.

And Mr. Ramirez cannot forget the awful images either, as he and his girlfriend, Rosanne Solis, huddled in fear inside the First Baptist Church.

“The monster was carrying two weapons, and aimed specifically at the little children,” said Mr. Ramírez in Spanish, shivering as he remembered how the tragedy unfolded.
