Evil Squirrels or Crackheads?

Evil Squirrels?
Originally uploaded by In Shaw

I grow a odd looking type of cucumbers, lemon cucumbers, so they are quite distinct and I think I’m the only one growing them in the hood. So yesterday, I was looking for a cuke that I was tracking the growth for and didn’t see it. Maybe I had harvested it and forgot.
Or not. Walking along Q Street I noticed this 1/2 eaten lemon cuke in a tree box and started screaming about the evils of squirrels. Those little furry agents of Satan that have been attacking my tomatoes, now are going after the cukes. Or are they? The fruit/veggie pictured is a little heavier than a tomato. Also this was found about 300 feet from the vine, a little far for a tree rat to drag away. So it is possible this is the work of a bad human.
Any other theories?
