She was seen talking to an unknown man... it's very common to read that on this website... overconfidence always goes further... a 15 year old girl still doesn't know what she's doing or who she's messing with... her family? Where was she? If she went with that man it would only be for a while before the guy got bored of her or she ran away due to mistreatment or a bad and miserable life... most likely she's dead, I don't think she'll last long like that...
I hope her final moment wasn't so painful...
whatever it is
rest in peace
