I decided the best way was to kill it with boiling water. It had a surprisingly strong reaction - it scrunched up really tight, then released and went limp - I felt really bad about it afterwards :(   I cleaned it's guts, which were somewhat translucent and portions were filled with sand. On the advice of the ladies, I threw the guts off the porch to the chickens, although I'm not sure how great my aim was... On a side note, the ladies said they saw the chickens eating a dog turd the other day, I guess they will eat anything. The final skin looked a bit like the stuff you would see in a Chinese supermarket, so I had quite high hopes this would work out.
