The culprit is Akiko Yohehara. Minako Mochizuki had found out that Sugiyama and another teacher (Shimoda, but she didn't tell his name to Yonehara) were involved in a fraud, and added that she was planning to confront the unnamed teacher. The poor girl was found hanged in the school gym few days later, and while everyone thought Minako had commited suicide under the effect of stress over the upcoming exams, Yonehara deduced that she had been killed by Sugiyama and his accomplice. Knowing the identity of only one of Minako's two murderers, Yonehara organized the trip to gather the teachers that she knew Minako was a fan of. She first killed Sugiyama and left his body hidden outside the lodge to freeze and trick people in regards to the time of his death. Later, she attacked Sonoko to have an alibi, then immediately afterwards pretended to be a victim as well (using Sugiyama's body to such effects, that's the "Yonehara" Sonoko actually saw before being attacked), and used her lipstick to spell out Minako's name in all of these cases. Shimoda's panicked reaction upon realizing the last detail revealed his involvement to her, so she tricked him into meeting up with her and killed him as well.

The murder weapon was Yonehara's wig: she had cut her hair too short for her liking a while ago and hid it via a very long wig, and then decided to use it to strangle her victims, excluding Sonoko as seen in the picture, without leaving clues. Ran says that there were small bloody scratches on the dead Shimoda's neck, and that there are be some droplets of his blood in the wig.

Once she's uncovered, Yonehara takes off the wig. She admits her responsibility for the crimes and says she couldn't forgive teachers who betray students and injure/kill them, but then she adds she's no one to talk because she harmed Sonoko to make her trick work.

Ran, whose emotional state had slowly taken a nosedive as Conan relayed the deductions to her, gets ready to leave the room, barely reacting to Mouri telling her that he'll write a great article on "her" deductions. She sees Conan standing outside the hall, ready to "tell" her that Shinichi is gone; before he can do so, she falls to her knees and hugs him tearfully. Two hours later the snowstorm stops, and the police arrives.

File 147 - Licking His Finger!?

Conan is assisting Kogoro with a game of Mahjong. When the fourth player leaves, they decide to call Mr. Hida, who works in the building across the street. Hida agrees to join the game but explains that he must first finish some accounting tasks. While waiting, they play a few practice rounds with Ran, who has arrived to pick up Conan.

After some time — with Hida having neither appeared nor responded to calls — they go to check on him. Outside his office door, they encounter an employee named Minamisawa; since he had left his mobile phone inside the office, he unlocks the door for them. When Hida fails to respond to their knocking, they force the locked door open and find him lying dead on the floor.

Inspector Megure, arriving at the scene, determines that Hida was poisoned between 7:30 PM and 8:00 PM. As both the windows and the door were locked from the inside, it appears to be a "locked-room murder." Conan suggests checking the surveillance camera footage; however, it only confirms that the victim was alone the entire time — after his employees had left the office. Shortly thereafter, the employees suddenly reappear at the office. The police discover traces of poison on the victim’s thumb, on several banknotes, and on the door. Conan surmises that Hida left his office while counting money and, in doing so, came into contact with an object outside the room that had been laced with poison.

File 148 - She Used Magic!?

Inspector Megure instructs the forensics team to search the entire office for traces of poison. He orders Takako Fuji — who is in the middle of preparing tea — and everyone else present to stop touching anything. Furthermore, all the suspects had visited the restroom while Ino was working at his computer. Each of the three suspects has a motive to kill their boss. Since no further traces of poison are found at the crime scene, the suspects' personal belongings are also examined, but nothing is discovered there either.

Conan reviews the case, reflecting on the employees' behavior after their arrival. When the forensics team reports an unusual discovery related to the traces of poison, Conan realizes that the key to solving the case lies in the restroom. In a small cabinet, he finds a bottle of bleach that had been used shortly before.
