Old mesh that was deleted still showing shadows after bake and collision from it

An old place holder is still causing collision and casts shadows. It was even deleted from the content browser. I have no idea how to fix this.

I checked wire frame and viewed collision, but nothings there. Can anyone help?

Apparently there was a ghost mesh. I found it buried in the outliner. Fixed the problem.
