Makes you really think about that one person in your office that could go postal at any time….

From Fox News:

Call it a tale of revenge gone wrong.

When Marie Lupe Cooley, 41, of Jacksonville, Fla., saw a help-wanted ad in the newspaper for a position that looked suspiciously like her current job — and with her boss’s phone number listed — she assumed she was about to be fired.

So, police say, she went to the architectural office where she works late Sunday night and erased 7 years’ worth of drawings and blueprints, estimated to be worth $2.5 million.

“She decided to mess up everything for everybody,” Jacksonville Sheriff’s Office spokesman Ken Jefferson told reporters. “She just sabotaged the entire business, thinking she was going to get axed.”

It didn’t take Steven Hutchins, owner of the architectural firm that bears his name, much time to figure out who’d done it — Cooley was the only other person who had full access to the files.

Police arrested Cooley Monday evening and charged her with causing greater than $1,000 damage to computer files, a felony. She was bailed out the following afternoon.

Hutchins told one TV station he’d managed to recover all the files using an expensive data-recovery service.

As for the job, Cooley originally wasn’t in danger of losing it. The ad was for Hutchins’ wife’s company.

The firm told FOXNews.com that Cooley no longer is employed there.
