awe 45 phx to kona diverted.

I was listening to a live atc feed when I heard US Airways flight 45 asked if they wanted to declare an emergency and tracked it back to phx on flightaware. I never did hear a reason for the diversion and wonder why. Judging by the fairly rapid descent maybe loss of cabin pressure? I’m just speculating.
