Narrative:

We were in a descent to cross ridge intersection at 11000 ft. Our speed was 250 KTS. As we entered the broken clouds to overcast, we were not showing any echoes on the radar. Turbulence was light initially, then we experienced a moderate bump. We requested lower immediately, the seat belt sign had been for the entire flight. The captain had made a PA prior to entering the cloud deck and reiterated to everyone to fasten their seat belts. Also he told the flight attendants to discontinue their service. One passenger on the last row did not have her seat belt on. When we hit the bump she hit the ceiling. Also the flight attendants were up trying to stow the service carts. We requested paramedics through the company and landed with no further incidents. Supplemental information from acn 269296: passenger in rear did not have seat belt on and was thrown against the ceiling which resulted in a small cut on top of her head. The flight attendants were also hurt in the process of trying to put away the serving cart. All were checked at the aircraft and were sent to hospital in tpa for further examination. The flight attendants were released and returned to the motel. I had no further information on the passenger.
