They Took Everything Except This One Odd Thing!

They took everything in my house. Except the one thing that means everything to my family. They didn't take our picture of my family that i got my sister for her birthday. Why didn't they take it? Could this be a clue that we will probably never find out why? I have tons of questions they need to answer and i bet they will know them. The police will probably find who it was and i think i have a idea who it is. But who would want to not take it?
