This is a first 'emergency' email of this sort that I've ever received:
That's the law school.
There has been a report at approximately 10 a.m. Wednesday, January 27, 2010 of a man with a gun in his waistband on the eleventh floor in the elevator of the Rubloff Building on the Chicago campus. The man is described as a white male wearing black jacket, blue jeans and a button-down shirt. All persons in the Rubloff Building should stay in their offices and lock their doors. Members of the Northwestern University Police Department and Chicago Police Department are currently searching the building.
later:The intensive search process at the Rubloff Building on Northwestern's Chicago campus has been completed, but police remain on site and are continuing to investigate. People in the building no longer must remain behind locked doors and are being allowed to move about in the building. However, access to the building remains restricted.
