Yes , this is so sad ! I feel for her family. This will haunt them for a long time to come.
I too aggree with Whiteknight. There's so much more here. Stress from her everyday life, problems back home maybe, and with her loosing the money, was all she could take.It must of been a large amount of money.
Makes me believe that what ever awaited her back home, she wasn't ready, or going to deal with it any longer.
