Ex-Firefighter with a scarred past. Search and Rescue with a medical background. He's been around the worst of humanity within the slums of several different cities. He's also seen incredible kindness come from people with no reason to show any.
Part of a team to help train SAR personnel over seas, Alex traveled to Chernarus to train emergency services there. When everything started going to shit, he maintained a dedicated group to control fire outbreaks in the city holding out hope that the military would get the infection under control. At an apartment complex fighting a new fire, a gas main exploded very near to him, knocking him unconscious. He woke up a few days later sore and stunned, but otherwise unhurt. Still in full firefighter gear, he set out searching for survivors.
