Haigney was the security coordinator for Bledsoe's group at 14633 12th Street, where Dana Walsh was water-boarded to reveal information about her conspiracy with Pavel Tokarev. Haigney checked in with the roof sentry Mullins and was unaware when the guard was later ambushed by Cole Ortiz and Jack Bauer. When Haigney was tricked by Bauer to believe that Mullins was taking sniper fire, he sent almost all the security contractors to the roof. Haigney was then confronted by Bauer, and revealed the location of Walsh when threatened. He was subsequently punched unconscious by Jack.
