Night of Witnesses

We were invited to a villa in the mountains far away from the world, but the owner was brutally murdered that night, and the murderer was among the invited guests.
In order to ensure our own safety and cooperate with the police who have not yet arrived at the scene to handle the case, we have to stay here until dawn.
If nothing is done, the killer will surely continue to kill other guests.
Talk to all the guests and vote to lock the suspects in the boiler room in the basement until the police show up. Everyone collected what they witnessed before the master was killed, and discussed and reasoned about whether the case could be revealed and the real murderer could be caught. Players take turns to secretly decide their own character, choose one character card from the character card passed by other players and the character card they draw from the top of the character deck, and pass the remaining one. For any player who has not yet decided on a role. Repeat this step until all players have decided on a character.
All players discuss the witness information about which character card went to which player's hand (location) and where it went later (location), and then deduce the location of the killer.
However, players who choose "Murderer" and "Accomplice" will never reveal their true identity. They may fabricate false witness information and turn the focus to other innocent people. After the discussion, a vote will be held. If the player with the highest number of votes is a murderer, the murderer and his accomplices fail, and all other players win. If the player with the highest votes is not a murderer, the murderer and his accomplices win, and all other players fail.

Guests were invited to a remote mansion in the mountains. However, the owner of the mansion was killed later that night. The murderer is sure to be among the guest, but who is the killer?

Each of the players first draws a character card. The first player then draws another card from the pile, keep one, and pass the unpicked card to the next player. The next player also keeps one and pass the other card until everyone gets one card in their hand. The last card would be passed to the "guest room".
The Player now has to discuss and vote for who is the killer or whether he is in the guest room.
