MAJOR GIRL PROBLEMS!!! :/?

My girlfriend was really annoying so I killed her. I didn't want to make it quick because she was really annoying so I went into the shed and brought out many items to do my bidding. I started with the rake, creating about an inch deep scratches down her abdomen, it was a sharp rake ;). I then proceeded to shoot a nail gun into her mandibles until she passed out from pain or died maybe? Anyhow, I chopped her up with a chainsaw and don't know how to best get rid of the body. Anyone been in the same predicament and can offer advice? Thanks, a guy with girl problems.
