MALIBU, Calif. --Corrections officials say an inmate firefighter has died a day after she was struck by a large rock while battling a brush fire in Southern California.

 

   Shawna Lynn Jones was airlifted to a hospital with major head injuries. The state corrections department said the 22-year-old was taken off life support Friday after her organs were donated, as her family requested.

 

   Jones is the third inmate firefighter to die on a fire line since the corrections department program began in 1943.

 

   She was a Los Angeles County jail inmate who joined the state firefighting program last year.

 

   Inspector Randall Wright of the Los Angeles County Fire Department says she was hit by a rock that fell about 100 feet from the hillside above her in the Santa Monica Mountains above Malibu.
