Missing person

Hello,

My partners grandma lives in Germany for many years. Saturday 6th of April she went to Moldova with her car to see her son . Unfortunately that was the last day anyone spoke to her and since then we don’t know anything about her and of course we are very very worried….

Last message from her was about her being on the road in Prag ( not too far from Australia border) .
We genuinely don’t know what to do in this situation. We live in England so there is not much we can do at the moment. I have called to different numbers to contact police in Germany but they are not helpful.

Any more suggestions what can be done in this situation please?

The most bizarre thing happened few hours ago when her WhatsApp picture got changed to this picture…

I know there’s only tiny tiny chance but maybe anyone knows who is the person in this picture?

Like why would anyone want to use her number, her WhatsApp . It’s like a sick joke . I have looked in google reverse pictures but there’s no results found.. we are worried sick 🥺
