Impostor Identification (Posted on 2014-01-15) Difficulty: 3 of 5
An impostor's identity is being investigated. The impostor is known to be one of three people: Andy, Barry, or Cal. The three people make the following statements:

Andy
1. Cal is the impostor.
2. Barry's first statement is true.

Barry
1. I am not the impostor.
2. Andy is the impostor.

Cal
1. Andy's second statement is true.
2. Barry's second statement is false.

However, it is known that the impostor makes one true and one false statement but the truthfulness of the other two suspects is unknown.
Who is the impostor?
