I'm curious, what does her being an architecture student have to do with this?
Just going by my experience, but it seemed the architecture students weren't the brightest bulbs...and it seemed that many would augment their creativity by illegal chemical means, and generally seem to have some real problems.
They did, however, seem to work long hours. Maybe Miss Ashcraft is giving an answer what those long hours were spent on, though.
I'm curious if they had any reason to link this baby's body to her, other than the previous incident and location.
