assigned to the case is Larren Lyttle, an old friend and colleague of Horgan's who has an acrimonious history with Molto. The prosecution's case against Rusty, which failed to definitively prove his affair and thus lacks motive, relies on circumstantial evidence: a bar glass with his fingerprints, sperm that might be his in Carolyn's vagina, carpet fabric that might be from his home, and records of a call from his home to Carolyn's apartment on the night of the murder, along with his attempts to seemingly impede the investigation. However, just as the trial begins the prosecution is forced to admit the glass is missing; Larren refuses to delay until it is located. As the trial ensues, Rusty learns through his and Lipranzer's independent investigations that Lyttle also had an affair with Polhemus, and that she acted as a courier in a bribery scheme where Lyttle was paid by defendants to let them off in court. Stern, while subtly threatening Lyttle with his own knowledge of this, is able to discredit a forensic expert's testimony regarding the sperm sample and inconclusive witness statements, persuasively arguing that Molto, who was aware of the bribery scheme but not involved, has fabricated evidence to frame Rusty out of misguided loyalty to Carolyn. Without proof of the affair or that Rusty had been in Carolyn's apartment the night of the murder, Larren sees no reason to continue and dismisses the case. Time passes and Rusty's relationship with Barbara worsens, after the trial had seemingly repaired it. When she announces her intention to leave him and take their son, Rusty explains his deduction that she killed Carolyn, as revenge on the woman who nearly destroyed her family; she admits that he is correct. During a visit to Rusty's house, Lipranzer reveals that he has the missing bar glass, which came about due to careless mismanagement by Molto and Lip's own disinterest in aiding the prosecution. Rusty talks Lip through how and why Barbara committed the murder while thoroughly cleaning the glass, destroying the only real evidence against him. They speculate whether Barbara left the glass at the scene because she wanted Rusty to know what she had done, or because she wanted him to be convicted. Rusty ultimately decides it doesn't matter, as he cannot bring himself to deprive his son of a mother and, except for Lip, will never admit the truth to anyone.
