WESTMINSTER, Md. (AP) — Prosecutors filed an appeal challenging the dismissal of charges against five counselors at a school for juvenile offenders who were accused of waiting more than half an hour before calling 911 about an unresponsive student who died.

The counselors at the now-closed Bowling Brook Preparatory School had been charged with reckless endangerment in last year's death of 17-year-old Isaiah Simmons. Circuit Court Judge Michael Galloway dismissed the charges last week.
