New details emerge this week as survivors of the massacre at Santa Fe High School speak out for the first time since the shooting.
The gunman killed eight students, two teachers and wounded 13 others when he burst into an art classroom with a shotgun and a .38-caliber revolver, both owned by his father.
According to witnesses, "He was playing music, making jokes, had slogans and rhymes he kept saying," student Trenton Beazely said of the suspect on "Good Morning America." "Every time he’d kill someone he’d say, ‘another one bites the dust.’”
Beazely recalls that he first heard a singular "boom" that morning in art class, he said, which he figured was a textbook falling to the floor. Then he heard two more "booms," after which "everyone just started taking off running,” he added.
