Jessie was an orphan, her parents left her in a foster home since she was a baby so she doesn't even know who her parents are nor does she care because in her mind, they abandoned her to her own good.
When she was twelve, still living in an orphanage, a musician that used to play in a famous band from there came by with a lot of instruments that he bought for the kids to play and practice, he started to go there two days a week to even teach them, Jessie became in love with the bass since the first time she heard the man play it, so she started to practice even alone, improving with it until she was invited by that man to play in a band of young teens that he taught.
And no one ever adopted her so she turned eighteen and had to leave the home she had, but immediately, the friends she did in the band, offered her a home which she of course accepted, having to share a house with three friends didn't sound so bad.
She traveled to Chernarus for some vacations with a friend that moved up there a couple months ago, he said he had some family that offered his lazy ass a home and a job. That guy was a guitarist in one of her rock bands in her home country that decided to quit, maybe because playing in random pubs with a band didn't payed the bills. Well, even Jessie had trouble with that and had to work half-time in a clothing shop, but she was happy doing so.
Now in Chernarus, the visit to her friend was going well, everything was so calm in that city not even being close to Capital of Buenos Aires. She enjoyed that, the fresh air, being with someone that she had missed, the visits to beautiful places like some castle ruins, the forests, and the mountains from there. But it all had to come to an end, and she had decided to leave after a little over a week because she was running out of money.
But one day after she had to leave, the city that was once so calm was filled with screams, gunshots, car horns all at once and she soon knew why, when she looked through the window she saw how everyone was freaking out, attacking eachother, people without a limb, even some of them being shot that continued to run agaisn't their prey, acting like wild animals, why whas this even happening? Didn't matter, all she knew was she had to flee from there as fast as she could. Though, she had to do it alone, her friend was working in the factory, where all of those crazy people were coming from.
She didn't even had the time to grab anything, she just went out the door to start running away, leaving the city as soon as she could to start wandering alone in seek for help, not even being able to speak the native language there was difficult, so she was left alone, following the masses of people where she assumed she was going to be safe.
