The pack consisted of Toni Elías who was leading the race, followed by Simone Corsi, Julián Simón, Tomizawa, Alex de Angelis, Scott Redding and Jules Cluzel.
As the pack approached Turn 11, the very fast right-hander that is taken nearly flat out, Tomizawa lost control and crashed.
He was thrown off his bike and onto the track, and de Angelis and Redding who were right behind both hit the Japanese rider at full speed.
de Angelis walked away from the crash uninjured, but Redding and Tomizawa were taken to the medical center, the Japanese's conditions appearing critical; despite this, the race was not stopped.
[2] Tomizawa was then rushed from the medical center to the hospital in Riccione, where he was pronounced dead at 14.20 local time, due to the injuries sustained in the crash.
