Albert, Barney, and Curtis were questioned about the murder of Dwight. Evidence at the scene of the
crime indicated a lawyer might have been implicated in Dwight's murder. Each suspect made two statements, as follows:
- Albert said he was not a lawyer and that he did not kill Dwight.
- Barney said he was a lawyer and he did not kill Dwight.
- Curtis said he was not a lawyer and a lawyer killed Dwight.
The police subsequently discovered that only two of the statements quoted above were true, and only
one of the three suspects was not a lawyer.
Which of the suspects killed Dwight?
