Dichotomatic Timeline: Murder Report #5

[King V]

Circumstances Before Death:
Everyone wakes up in the morning to find that a small blood trail is going through the guest corridor. Everyone splits up into 2 groups and each follows a different side of the blood trail. The first group arrives at the Attic where Mystio unlocks the padlock with the Master Key. They rush inside to find Koishi lying on the floor in a pool of blood.

Victim: Koishi

Cause of Death: The victim has a large hole in their chest which is bleeding profusely. The gag and ropes binding the victim are untouched.

Time of Death: The body was found by the first group arriving at the Attic at around 8:30am in the morning. Mystio unlocked the padlock with the Master Key, and the body was found inside.

Location: The victim was found in the Attic. A small blood trail led from the guest corridor to the Attic. All windows in the Attic were locked when the body was found, and the padlock was also locked when the group entered.

Investigation: The first group immediately heads down to call the second group, but they're called by the second group first. Everyone meets up at the entrance to the Kitchen where the blood trail seems to lead inside. The door to the Kitchen is locked, but it is broken down easily. And inside, everyone finds the blood trail leading to... the body of Koishi lying in a pool of blood in the middle of the Kitchen. There is an argument about the body, and everyone rushes up to the Attic to find that the body of Koishi is gone. All windows in the Attic and the padlock were all locked at this time.

Everyone immediately heads back down to the Kitchen, but finds that the body is missing from the Kitchen. All windows in the Kitchen were found locked at this time. A new blood trail was found from the pool of blood where the body was originally leading out of the Kitchen. Everyone follows the new blood trail to the Mansion Entrance where they find Koishi's body lying on the staircase.

For reference:

First Group: Mystio, Bobby Fullbright, Shiori, Ririchiyo, Kouta Tsuchiya

Second Group: Blitzcrank, Iris Ashberry, Spy W, Dr. Faust, Ai Enma

When the first group went to call the second group did they lock the attic?

[King V]

Of course the Attic was locked by Mystio every time any of the groups exited it.
