Found sturdy black roller suitcase with a lock near St Joseph beach.

I found a sturdy black roller suitcase this morning near St Joseph beach. It had a few scuff marks but looked otherwise intact. The suitcase was left unattended at the edge of the walkway; I couldn't find anyone nearby. It has a lock on it, but I haven't tried to open it in case it belongs to someone who might want to claim it. Hopefully, the owner realizes it's missing and can reach out.
