(ORLANDO SENTINEL) — MINNEOLA, Florida — A Lake Minneola High School student described by a friend as “a really nice kid” shot and killed himself Tuesday morning in the school’s bus loop during a fire drill, school district and sheriff’s officials said.

The student, identified this afternoon as Seth Sutherland, 17, had been separated from other students, authorities said.

“It does not appear anyone actually witnessed it,” sheriff’s Lt. John Herrell said.

Dozens of panicked parents who hurried to the school with about 1,800 students, which had been placed on lockdown following the shooting, finally were allowed to pick up their children starting at 11:10 a.m. so long as they had their IDs and were on the pickup list created when they registered their kids.
