Why didn’t he feed her too the pigs?
Maybe because he didn’t do it, and John Cannan did. The hog farmer would know he could feed her to the hogs and it would look like an accident, like she slipped in a pen while helping with chores, but it looks like John Cannon didn’t know much about hogs. Maybe he’s a plumber.
Good question!.....Too slow and possibly pieces left behind?.......But he would have had an excellent alibi because people being eaten by hogs is not unheard of................
