the story's end

 I love it when a plan comes together.

Here's a better photo (taken with more light) of the offender. I've texted the woman at animal control, hopefully she will text back soon that she's picking it up. If I don't hear back before I get out of class I might try calling the number in case something went wrong with her texts.

Update: Animal control texted me, the opossum has been "relocated to a more suitable area" and I don't think she was just feeding me a nice fiction because I told her I was a biologist; I think they really did drop the little guy off out in the woods.
