I have had the same problem, living with my mother when I was younger we were burguled 5 times! And they always knew where to look or would get a specific item, we were made aware it was an inside job and worked out in the end it was my mothers friend! Things can be replaced, but I know if it is sentimental it is irriplaceable, but at least you were not hurt and in the end that is all that matters. I am soo sorry this happenend to you x
