Deleted photo keeps coming back on my iPhone

I am having problems with my iPhone 4s storing a photo I deleted a long time ago, both from the iPhone itself, and manually from the photostream on my mac. It no longer seems to show up on my Mac in photostream or events, but shows up on my iPhone as its own event. There's no way to delete it from the iPhone event itself, so it appears that I am stuck with it. I am at a loss for where this photo is even syncing from, as I have already deleted it both from the device itself and from my mac....Sort of bizarre how difficult it is to get rid of photos once you take them.

I have also already tried turning on and off my Photostream on my iphone, resyncing manually by attaching to my computer and resetting my iCloud Photostream.

Any other suggestions or ideas on how I might get rid of this??
