Now that 773 is out, we now know somewhat of the truth.
Guess, we'll have to toss the suicide theory out the window.

And the rat being the murderer is just.......too simple. Hopefully, this means the rat ISN'T the murderer. =.= You're right that Tamami's actions look too nervous just to make her, being the rat, look like it's "obvious" that she has done something wrong. *crosses fingers*
You still have a chance with your theory of the rat not being the murderer. ^____^
*starts to imagine*
*Beginning of Part 4, the conclusion*
Sera: "Ho. Now, here's the moment of truth. Right after pointing out that she's the Rat, he will now explain how she's killed Miku-san. This will definitely buy us some time.*
*Sera smirks*
Conan through phone: "It can be none other than YOU!! BUT, she is not the murderer."
*Sera's smirking shrinks*
*Sera stops smriking*
Sera: *What are you doing!? Now, he's really going to....!!*
Sawaguri: "Stop messing with me!! I thought you were agreeing with me that it was the Rat!!"
Conan: "I said that she was the Rat. That is all. She witnessed your sister passing out. Even though Nihei-san had a small issue with your sister for being untidy, she wouldn't go to far lengths as to thinking of murdering her. Yuchi-san couldn't be the murderer, because she clearly said that she'll be back. Mitsui-san appears to also have a small grudge with your sister for her personality, but, it would seem too easy for her to be the murderer as she's very close to Miku-san's room. Not to mention, she was the last person out of the room. The truth is none of them are the murderers!!"
Sawaguri: "What!? Noo... This can't be! You have failed me, Detective!"
KA-BOOM
Back in Prof. Agasa's house.
.....................
Ai: "Great job, Mr. Detective. You got your girlfriend and everyone else killed."
*Conan drops the phone in shock*: "No---nooooo!!"
*Suddenly, Sera's voice is heard on the line*
Sera: "He-hello? Anyone there? Shinichi-san, I presume?"
*Conan suddenly picks up the phone*
Conan: "You're alive!?"
Sera: "Yep. You see, the police threw some sleeping gas grenades into the detective agency and I managed to cover my mouth with a cloth. Everyone's doing fine." ^____^
Conan: "........"
Sera: "Not to mention, this was done because fan readers are in disbelief that Mitsui-san is the rat. They think it's too simple and easy. So, someone incepted an idea into Gosho's head to make it so no one is the murderer."
Conan: "......."
Sera: "Shinichi-san? Are you there? Hello?........Conan-kun?"
Conan: *snaps out of shock into new shock*
>> End of Fictionary File number 4. Never to be continued due to its violation of Gosho's imagination.
Isao: NO! That can't be true! My little sister wouldn't be that cruel!
Tamami: SHE WAS!!! I've an evidence that she did that. I've tried to live with my loss, but the pain was just too much for me, that's why I killed her.
Isao: What a cuttie pussy cat~! Meow! ^o^ You know, Tamami, I understand you. My sister deserved for that. Let's forget about it and go to bar. I must say, you're really hot woman, Tamami. ^_^
Tamami: Oh, Isao, you little rascal~! ^o^
The others in the room: O_o What the...
Police outside: O_o What the...
Sera to Ran: You're still sure that killing him would be that bad?
Okay, maybe this was too unrealistic... Hehehe... -_-'
Let's try something more probable. Possibility 3:
Shinichi: Tamami is a rat, but she's not the murderer!!!
Isao: WHAT?! How could it be? Wasn't Tamami the last person who saw my sister alive?!
Shinichi: That's right, but she's not the murderer. Though, she saw something she shouldn't have seen. Am I right, Tamami? Tell us, why you was so scared when you left Miku's room.
Tamami: -_-' Didn't I say that I had stomach problems? I had to go to the bathroom.
Shinichi: O_O What? Really? Dammit! I thought that you saw how Miku fell asleep and escaped!
Tamami: No, I really had stomach problems.
Shinichi: But, but... Maybe you saw something! Anything!
Tamami: Nope.
Shinichi: Looks like I don't know who's murderer. Probably it's Tamami. Whatever. I need a break, maybe I should go to Hawaii?
Sera:
Oh, my... I made another weird story again... I will try again soon, cause today I've too idiotic ideas, I guess.
