Honestly, as much as I love Rollo, there is at least a 99% chance that he did do this. I don't know where the Suzaku theories came from since, even though I dislike him, I think he along with Lulu are the least likely to have done it.
Also judging by Rollo's actions and responses to Shirley's questions, I think he indeed more than likely freaked and shot Shirley because when situations like that arise, it's only natural for him to respond like that after many years of living as an assasin who kills for sometimes no reason. That and he didn't seem quite pleased with Shirley in the last episode all that much~ Jealousy anybody?
I also highly doubt that it's suicide.
So yeah, my other crack theories that would make up the 1% are it was Sayoko because we have no idea what happened to her after Rollo left her on the helicopter and we all know she was jealous when Shirley went for Lelouch instead of her... XD either that or she was afriad for dear Lelouch and when she over heard Rollo's and Shirely's conversation, she figured she knew too much about Lelouch and decided to kill her :P
Another would have to be based on Shirley's dream itself >:D Villetta. Shirley felt guilty all this time, so when Villeta shot her, she didn't mention it to Lelouch and her dream was actually a premonition and you knw what case solved! Even though Villetta has her Alibi of talking to Ougi, we all know it was her! XD
I don't care if Rollo did it or not. I still love her crazy character to bits and just hope he doesn't die in the series D:
