Umineko no Naku Koro Ni - Died

[JDGA]

/in
This cannot possibly end poorly

[JDGA]

Are we allowed to do things with info we wouldn't know about? (Like question Luka about saying the suit wasn't in any guest's luggage)
And do we know the map is a 100% accurate representation of the entrances/exits (ie there are no secret passages)?

[JDGA]

If it's a love interest, just make them lesbian :3

[JDGA]

Anyways, everyone's here? I'm gonna start by asking everyone about their whereabouts and alibis.

[JDGA]

I look at everyone else in the meantime, making sure they're okay (and that no one tries using the distraction for anything weird)

[JDGA]

"They're definitely dead, right? This room's a wreck, can we leave them here and stay away from it? Perhaps we can seal up the room too and go somewhere else... but we all

need

to stick together."

[JDGA]

Looks like we've got the door into the ground floor hallway, the door into the kitchen, and three windows to the outside.

[JDGA]

So pretty much no one's got an alibi, so the main question is how was the locked room murder committed.

There are more than two keys that can open the dining hall's door

(since we've got two in the envelope)

The suspect hid in the dining hall or kitchen after committing the murders, and sneakily rejoined the group when the bodies were discovered
The suspect left through a window after committing the murders
The suspect left through the kitchen after committing the murders
The suspect was able to kill while not being in the dining hall or kitchen
The suspect is Luka, who lied about the door being locked

That should be a good enough start for now~

[JDGA]

The culprit is a servant, who obligingly locked the door behind them.
There are more than five master keys in total, and the one in the envelope did not belong to any of the servants.
Fracie's master key was taken and used to lock the door.

[JDGA]

^ If the detective isn't able to do that, consider me to invoke my power to ask you to repeat that.

In the meantime,

The door was locked from the inside with the dining hall key, which was then placed in the envelope. The culprit then hid in the kitchen for the bodies to be discovered and stealthily rejoined the group at that time.

And while we're at it,

It is impossible to solve the riddle in the envelope with the clues currently presented.

[JDGA]

The culprit went through the kitchen window.
The culprit had the aid of an accomplice.
There is another key that can lock the dining hall door besides the five master keys and the dining hall key in the envelope.

[JDGA]

There are no more than twelve living humans on the island presently.
All twelve living humans entered the dining hall through the dining hall's main door at some point after Luka unlocked it and discovered the bodies.
The culprit is one of the six victims.

Repeat it in red:

The culprit had the aid of an accomplice.

[JDGA]

The murder weapon was disposed of in the kitchen.

[JDGA]

The murder weapon is still in the dining room.

[JDGA]

There is no murder weapon.
The murder weapon left the dining hall through a window.
The murder weapon left the dining hall through the dining hall's main door.

[JDGA]

One of the victims (an accomplice) lived long enough to lock the door and seal the envelope before dying.

The only keys which can lock the dining hall's main door are the five master keys and the Dining Hall's key.

"Flaming, where else could it be? We didn't find Fracie's master key on her either, but one was in the envelope..."

[JDGA]

"So you think someone's stolen it?"

[JDGA]

Well then, let's search the cabinets and refrigerator and all the places a person or body or knife could be~
