Olsen was a CIA operative posing as a Daily Planet photographer. Olsen accompanied reporter Lois Lane to Nairomi, where she was assigned to interview terrorist General Amajagh. The two were escorted to Amajagh's headquarters but not long into Lois's sitdown, Anatoli Knyazev grabbed Olsen's camera. He smashes it to reveal a tracker hidden inside.
Olsen was forced to reveal his true identity and claimed Lois had nothing to do with his assignment. He told Amajagh that he was there to strike a deal with him, but the general was having none of it. He shot Olsen dead.
