Does Cinna die in Catching Fire?

Cinna is killed in Catcting Fire but his death is confirmed in Mockingjay. As Katniss is about to enter the arena once again for the third annual quarter quell, a few peacekeepers come in and beat Cinna to death. Katniss can't do anything but scream because she is in the glass cylinder. Cinna was my favorite character after Rue got killed so of course I was sad.
