19. "Rashomama"- Diane's death was ruled to be caused by a subdural hematoma, or brain bleed. This was caused when Diane was pushed backward onto a statue of a cupid and arrow. Who pushed Diane?
From Quiz It's A Wrap -"CSI" Season 6 Final Four Pt. 1
Answer:
Lacey, the bridesmaid
Lacey followed Diane into the dressing area, after Diane had stumbled out of the reception. Once they were both in the room, Diane threatened to have Lacey charged with conspiracy to commit murder. The CSIs had determined that Diane's Diazepam levels were in between therapeutic and toxic, so Diane may have been right on the attempted murder scenario. Lacey became very angry, and she pushed Diane back, accidentally impaling Diane's head on the cupid's arrow. She then went back to the rest of the bride's party and asked those women to help her get rid of Diane. They decided to tie Diane to the "getaway" car and make it appear as if the Fatelli brothers were the ones who'd killed her.
In the end, all of the women admitted to their role in Diane's death. And, while her death was not the intended end result, they admitted it had not really bothered them that she'd died.
Amanda Seyfried played Lacey. Amanda starred in the movie "Mean Girls" and on season one of HBO's series "Big Love".
