Anybody had anything stolen by UPS?

[Mr. Pink]

Shipped a pair of rare skis to a friend in Denver. My bad, screwed up the address, couldn't deliver, sent back to where ever they park a bad address. Fixed the address, but now I'm being told they are officially lost, and an investigation is under way. That was four days ago. I suspect theft at this point, but still have hope. Could somebody actually get away with this inside the system? Final address is a UPS store, so, no porch thieves involved.
