Mr. Carpenter (Mark Consuelos) as the 4th accomplice to Maureen's death

What if we get a flashback to 1995.
Roman, Billy, and Stu are in a car discussing the plan. The driver turns around and it's Mr. Carpenter (Mark Consuelos). He says he will be waiting in the car for them.
He is hurt that Billy and Christina would betray him like that, so he decided to punish their daughter by telling Richie and Amber.
