Reasonable Doubts

S1, E15: When Annabeth has to prosecute a man for killing his mother-in-law, his defense attorney creates a case against his own wife by claiming she committed the murder in order to establish reasonable doubt for the jury. The judge throws out the defendant's testimony after his lawyer claims that he was not given legal counsel during his interrogation. When Annabeth learns of a hidden secret in the defendant's past which easily explains why he killed his mother-in-law, the defense tries to deliberately mislead the jury into believing the defendant's wife committed the murder in order to create doubt.
