My iPhone got stolen.

To be specific, My iPhone was stolen at 11:(some time) while I was in walgreens. And I noticed it got stolen the day after the incident. I looked for it everywhere. I told the manager of the store about what happened and he said that no one gave them any stolen phone. Then I asked to see security footage. But they told me only the corporate has access to the footage. But I have an iPad, so I used the "find my iPhone" app, sadly, it could not find it. So I filed a complaint to the police. The news is still pending but I doubt they could do anything about it. What should I do now?
