A murder has been committed in a house. You are a detective and have to find out the murderer.

You investigate by asking three questions to each of the six suspects. Out of those six suspects, four are liars. It is not necessary that they speak everything a lie. But in their answers, there must be at least one lie. One of the six is the murderer.

There are eight rooms in the house in which the murder has been committed: Kitchen, Living Room, Bathroom, Garage, Basement, 3 Bedrooms.

At the time of the murder, only the murderer was present in the killing room. Any number of people can be present in any of the other rooms at the same time.

Can you identify the murderer and the four liars? Also, can you find out who was in which room?

The responses of all the suspects are mentioned below.

Peter was in the 2nd bedroom.

I agree with Joseph that David was in the bathroom and Peter was in the 2nd bedroom.

Mandy was in the kitchen with Christopher.
But I was in the bathroom.

I still say Peter was in the 2nd bedroom and Jennifer was in the bathroom.

And Mandy was in the kitchen.
