Darker question...

I young girl I went to school with was missing... well I just found out she died. I’m not sure how but they asked families and friends to where black in her memory...... I know it’s typical to where to funerals but is there a deeper meaning I’m missing here?

Did she kill herself?

Murdered?

Edit:

All I know is she left work early one day and never returned home.. not alive anyways 💔
