Bank Robbery #1 - Logic Puzzles

After a local bank robbery, five suspects were interviewed.

Below is a summary of their statements.

Police know that each of them told the truth in one of the statements and lied in the other.

From this information, can you work out who committed the crime?

Billie said:    It wasn't Chris    It was Alex
Drew said:    It was Chris    It wasn't Alex
Chris said:    It was Billie    It wasn't Emery
Alex said:    It was Emery    It wasn't Billie
Emery said:    It was Drew    It was Alex

Answer
Drew.

Reasoning
Since each suspect told the truth just once, Emery's statements mean that it was either Drew or Alex.

If it was Alex, then both of Billie's statements would be true, which isn't allowed (and similarly both of Drew's would be false).

Therefore, it was Drew.

This can be double-checked with all of the other statements.
