This team meeting focused on ieda's for the Murder Mystery. The idea's that we came up with are as follows:
1. One person manipulates another person to kill people for him, without direct orders.
At the end of the story the people who are left find clue's that lead to deduce who the real killer is.
2. Two murders, The first murderer kills a victum, the second murderer kills the first killer
3. Accidental suicide, but the people dont know its accidental. Poisin drink.
4. Killer A kills Killer B with something, but Killer B has already poisoned some drink that Killer A is going to drink.
