The three defendants

The three defendants

Three suspects were undergoing an interrogation to locate the only one who was guilty of a robbery. Each of the three accused one of the other two. Of them, only the first told the truth. Pressed by the police, they returned to testify and now each accused someone different and no one self-accused. On this occasion, only the second told the truth.

Which of the three is to blame?

Solution

In the first statement, the first suspect tells the truth and accuses the second or third suspect so the culprit will be one of those two. In the second statement, the second suspect tells the truth and accuses the first suspect or the third. Thus the third suspect will be the culprit since it is the only one that the first two can blame when telling the truth
