Found light blue denim jacket with a keychain attached on the walking trail by the river in Lewiston.

I found a light blue denim jacket on the walking trail by the river where I often go jogging in Lewiston. It was just laying there without anyone around, and there was a small keychain attached to one of the pockets with some initials on it. I thought it might belong to someone who frequently walks in that area, so I'm hoping to find the owner!
