If you look at Lin's link

the pupa appears to have a kind of curly "tail". Does the suspect in question have that? I can't tell from the image.
This one on Bugguide is a more obvious "tail":

We have two threads going for this now, and I suggested on the other one that it might be a cutworm pupa, see:

Only way to be sure what it is is to keep one in a clear jar with a perforated lid and see what emerges from the case. Much easier to ID such critters as adults.
