It looks like a wild relative of currant/gooseberry - some ribes species.

That is what I was thinking too Scott. I just can't find any pictures on the internet that look like this to confirm.

And no sooner do I say that when I find this picture lol...

Looks like wild black currant?? The flower did look just like that.

Certainly one of the ribes from the leaf, but they usually fruit in clusters.
Could it be a Jostaberry, a cross between a black currant and a gooseberry? Looks too big for a straight currant. Did it ripen to black?
We have five bushes and they produce prodigious amounts of good tasting fruit.
