Delicate silver necklace with heart pendant

I found a delicate silver necklace this afternoon around 2:15 pm near Campus Martius Park along Woodward Ave by State Street in Detroit. It's a sterling silver chain about 16 inches with a small open-heart pendant and a tiny initial 'M' engraved on the back. The chain shows a bit of tarnish from daily wear, and the lobster clasp is intact. I picked it up thinking someone must be missing it and I really hope to reunite it with its owner.
