This has JUST hit the news (and I'm told it's already gone national):
School shooting at Perry Hall High
I truly hope the victim is alright, though they flew him/her to Shock Trauma so it sounds quite serious. They're evacuating the school, and parents can pick up their kids in the shopping center across the street. Local folks: if you know parents with students at the school, please make sure they know this information.
UPDATE: There are THREE evac sites: Perry Hall Shopping Center; the Middle School across the street; Joppa View Elementary. PLEASE get in touch with your child/ren and figure out where he/she/they are.
UPDATE: Honeygo Park is also being used as an evac site.
