Day 3[]
At the beginning of Day 3, Barham asked Rick Jackson about a certain case where Rick tortured a man to find evidence of an attack in progress. Rick was then pulled out of court to help find the Cordilla Virus.
Day 4[]
When Rick Jackson was being framed for Michael Harris' murder, he found out from Arnold Robinson that the CPA was being investigated by Barham, and that Barham would have the most information. When Rick talked with Barham, they found out that the CPA was in possession of a biological weapon. When the police banged on Barham's door looking for Rick, they agreed to open it. It was actually CPA assassin Bill Gaines, who killed Barham since he had information. Rick then fled the scene with the evidence on a thumb drive.
Barham is killed by the assassin Bill Gaines.
