Is there anyway to find out who deleted a folder on a shared drive?

I am suspecting that there is some professional sabotage where I work. A folder which held weeks worth of work was on a shared drive. The drive is accessible to everyone in the company. Yesterday it vanished. I’ve searched everywhere and cannot find it. I did not delete it, I checked with our IT guy and he didn’t move it… he’s looking into the back up to retrieve it, but half the work since the last tape back up will be gone.

Is there any way that they (or I) can determine who removed the folder from the drive?
