Members of the greater Newtown, Connecticut community react to Friday's school shootings
Some have relatives who attend or work at the school
People on Twitter posted images from the scene and from a nearby fire station
One simple tweet can help push the start button for action, thanks in part to the viral nature of social media.
Several people on Twitter expressed concerns about relatives who attend or work at the school, where a law-enforcement official said at least 18 children were slain after gunfire erupted Friday morning.
Others posted images from the scene and from a nearby fire station, where survivors were taken. A hospital in nearby Danbury posted a Facebook update late Friday morning saying that three victims were being treated there.
In what now seems like a much more innocent time, the school hosted a winter concert Thursday. Principal Dawn Hochsprung, who was killed in the shootings, had posted a photo on Twitter Wednesday of a rehearsal for the concert.
