From Halopedia, the Halo wiki
In March 2558, Captain Thomas Lasky, Spartan Naiya Ray, and civilian journalist Petra Janecek traveled to Kor Delban, Karava to speak with Petra's contact. 'Lordan felt challenged by Ray and drew his energy sword, prompting two other Sangheili to do the same. As Lasky tried to calm everyone down, Petra took out her revolver and shot 'Lordan in the head, killing him. Petra then warned the other Sangheili to back off. She then joked that this display of dominance had led the other Sangheili to believe her compatriots were actually her pets.
