Peter Kunz was the manager of a bank in Zurich.
Peter was seen alongsinde his boss when a disguised Sloane arrived to collect 50 million dollars. While walking, Kunz asked Sloane if he wanted something to drink, but he denied the request and the two continued to walk. When they arrived inside the vault, Julian asked Sloane to stall for another ten seconds so he could gain control of the surveillance system.
Sloane asked how well the safeguards of the bank were due to recent terrorist attacks and Kunz assured Sloane that the bank was as protective as it could be. Ironically, Sloane shot and killed Kunz the second he finished answering.
