Found black rolling suitcase with travel stickers near Lake Charles boardwalk containing clothes and a travel guide.

I found a black rolling suitcase while taking a walk along the Lake Charles boardwalk yesterday afternoon. It has a few travel stickers on it, and appears to be fairly new. I opened it to see if there was any identity information inside, but I only found some clothes and a travel guide, nothing that could help identify the owner. I would love to return it to its rightful owner if someone can describe it to me.
