RENO, Nev. (AP) -- The death toll in the crash of a World War II-era plane during a Reno air race rose to nine people Saturday as investigators combed through wreckage and scoured amateur video clips to determine why the aircraft suddenly spiraled out of control and plummeted to the ground near hundreds of spectators.

The deaths include seven who were killed on the tarmac, including the 74-year-old pilot, and two others who died at hospitals, Reno Deputy Police Chief Dave Evans said.
