Ronan said, when Quirrell was killing unicorns, that it is the pure 
and innocent who always are the first to die.

Cedric Diggory was the first to die this time around.

Cedric Diggory's wand has a unicorn tail hair at its core.

Only one other character is mentioned as having a wand with a unicorn 
tail hair at its core. Ron.
