What brand of bike is this? Schwinn Stingray?

I recently purchased an older 20″ street/casual riding bicycle at yard sale this past weekend. There are no labels on the bike to tell me what brand of bike this could be. We had suspected it to a Schwinn Stingray. The bike was repainted by the previous owner, so I can not see any serial numbers. It is a single speed bike with a pedal brake system. I noticed that the bars that run across the sides of the frame near the top taper at the tips near the neck. Whereas on a Schwinn they seem to not taper at all. I’m just curious as to what kind of bike this could be. Murray, Huffy, something else? Can you help me?

This is the only picture I have of it at this time.
I’m gonna have to do this tonight when i get home. My work computer will not allow me to add the photo to my photobucket page.
