Genoa-Kingston Superintendent Joe Burgess never considered that a staff member’s child could be a safety threat.

Leaders in his district review their emergency plans twice a year, but he said they’ll start an impromptu third review Monday in light of Friday’s shooting at a Connecticut elementary school that left 26 people, plus the shooter, dead. Media reports Friday afternoon indicated the shooter’s mother worked at Sandy Hook Elementary School.

“That school probably didn’t think anything about the child of a worker,” Burgess said. “... It seems every time you think you have bases covered, something else comes up. Any school official you talk to is going to tell you it’s our greatest fear.”
