Did Fla. middle-schooler plot to kill teachers?

CLERMONT, Fla. - Deputies in central Florida are investigating a possible plot by a middle school student to harm some of his teachers.

Officials said Thursday that the student at East Ridge Middle School in the Orlando suburb of Clermont is undergoing a mental health evaluation. No charges have been filed.

Deputies say the student brought a knife to school last week and had a black book detailing a plot to kill some of his teachers and then himself.

Deputies searched the student's home but found no other weapons.

Officials say the student had recently been suspended from school for 10 days and the school was looking for an alternative placement for him.
