The Pacific Courier truck was driven by Heinrich into the underground parking garage of Nakatomi Plaza, where it pulled into the loading dock and parked and everybody got out. Later on, Theo went down into the parking garage and got the getaway ambulance they had parked in the back of the truck earlier, prepared so they can escape the scene while the police think they died in the roof explosion. While he is getting his paramedics uniform on, however, Argyle who was also in the parking garage during the siege rams the ambulance with his limo and knocks him out.
