WASHINGTON, DC - Some of the Washington Navy Yard employees returning to work this morning say it's too soon for them to even talk about Monday's shootings that killed 12 people. Others say it will take a while to get past the tragedy.

The installation re-opened this morning at 6 a.m.

Judy Farmer, who works as a scheduler at the Navy Yard, admitted that she'd "rather not be here today.''

Barbara Smith said she was feeling apprehensive as she walked toward the entrance. But she added, "I have to work, and I'm trusting that they're taking care of what needs to be taken care of.''

A man who works in the Navy Yard, across the street from the building where the shooting happened, says, "It's a little surreal.'' Brooke Roberts says, "You don't think this sort of thing can happen to you at your workplace, so you're just not prepared for it, regardless.''

A Navy spokeswoman says today is a regular work day, except at the building where the shootings occurred and the base gym. The gym is being used as a staging area for the FBI to investigate the rampage, in which a former Navy reservist gunned down 12 people before police killed him.
