A Bergen County preschool teacher was arrested after co-workers told police she threatened to come into the school with guns and start shooting, authorities said Tuesday.

Gina Schroeder, 38, of Nutley, made the threat Friday at The Goddard School on Riverfront Boulevard in Elmwood Park, according to Chief Michael Foligno of the borough’s police department.

Schroeder is accused of saying, “One day, I’m gonna come here and shoot it up,” Foligno said in an email. A staff member told police Schroeder disclosed she owns three guns, Foligno said.

Officers placed the preschool on lockdown and the building was swept for weapons while the accused teacher was detained, Foligno said. No weapons were located in the building or in the teacher’s vehicle, the chief said.

Nutley police later searched Schroeder’s home and seized three guns, all of which were legally owned, the chief said.

Schroeder was charged with making terroristic threats and illegal possession of prescription drugs. She was taken to the Bergen County Jail, where she remained on Wednesday, according to jail records.

According The Goddard School website bio, which has since been removed, Schroeder had been with the school since April 2016 and was the lead teacher in the infant classroom.
