Die Hard with a Vengeance
Killed by John McClane
- "Wait until he gets alongside the door."
- ―Klaus to Nils
Klaus was inside the Federal Reserve Bank, disguising himself as a repairman working with the security system that malfunctioned due to the bomb that went off in Wall Street Station. When Simon Gruber and the others arrived, Klaus, along with Nils, break cover and pointed their weapons at the guards and possibly killed them. Klaus was in the hallway away from the control room, where the last security guard, fired at them to give them away, as they expected. When Katya finally kills the guard, Klaus and the others went to the vault room and help load the gold bullions to the dump trucks they stole.
Klaus rode with Nils on the Franklin D. Roosevelt East River Drive in a dump truck loaded with stolen gold bullions. As they both reached New York City Water Tunnel No. 3, they stood guard of the area until Simon calls them when they reached the cofferdam. Both of them heard dump truck that had John McClane and trucker Jerry Parks stop behind. As McClane steps outside, posing as an aqueduct security officer, Klaus tells Nils to wait and shoot McClane as he is alongside their truck door. This proves to be a fatal mistake however, as McClane shoots them through the door with his Beretta 92, which killed them both. McClane later takes their dump truck, gun and radio. Klaus was Simon's sixth henchman to die.
