Police say a suspect has been identified.
Gaithersburg, Md (KM) Montgomery County Police continue to investigate a series of bomb threats on Tuesday against county public schools.
They say the Maryland State Police received calls about bomb threats, and forwarded them to the Montgomery County Emergency Communications Center.
The calls led Wootton High School to institute shelter -in-place; and Einstein High School was evacuated while a search was conducted by police canines.
Through their investigation, Montgomery County Police say they were able to identify the number where the calls were originating as being associated with a psychiatric hospital in the Washington DC area. The hospital identified the patient, and is cooperating with police. Authorities say no charges have been filed at this time. .
