Jake was just about to become a policeman, when a family member in chernarus died.
He and the rest of his family took the next plane to chernarus to bury his grandfather.
Having a walk outside alone at night, visiting the nearby castle he couldnt know, what was going on in the cities.. it was when the breakout happened.
When he came back, he already saw parts of the city burning in fire, he ran back to their hotel, but the entire entry was full with dead bodies and in between some "dead" people walking and falling all over the bodies.
This was the time, Jakes story started.
