24878 Alvert Street

24878 Alvert St. is the address of a building that Dina Araz gave Jack after Behrooz was rescued from the laundry room during Day 4. Dina told Jack and Tony that the building was the location where everyone involved in the terrorist attacks picked up their final assignments. She said that the men behind the train wreck, the kidnapping, and the stolen override device did all their planning in the building.

When Jack and Tony entered the building, they found it deserted. Jack noticed a power cord that disappeared beneath a floorboard. He and Tony pried up several loose floorboards and found a hidden door leading to a basement. In the basement, they discovered schematics of the nuclear power plants, passenger manifests from the train that was bombed and surveillance photos of Secretary Heller and Audrey. Jack spotted himself in one of the photos on the wall.

Sarah Raven, a systems analyst at CTU traced the ownership of the building. She learned that the building was owned by a company that was owned by a company that was owned by an LLC called Galaxy Financial Services. She contacted Jack and told him that she recognized the LLC because the name had come up during a security clearance she had done for Paul Raines, Audrey's husband, earlier in the day.

When questioned about his connection to the building and the terrorist attacks, Paul denied involvement. He learned from his computer files that Galaxy Financial Services was taken over by someone named Harris Barnes.
