NYC substitute teacher allegedly threatened to shoot up class

A Queens substitute teacher was busted for allegedly threatening to shoot a class of middle schoolers if they didn’t listen to him Wednesday, according to police sources. 

Alejandro Rocha, 52, was teaching a group of nine kids, ages 11 and 12, at IS 5-The Walter Crowley Intermediate School in Elmhurst, just after 2 p.m. Wednesday when he made the disturbing remark, the sources said.  “If you don’t do what you’re told, I’m going to shoot you — and yes, I have a gun,” Rocha allegedly snarled.
