Who thinks this was in fact Charles Wallace Jr? and who thinks it was Bayard Cousins?
I definitely don't think it was Bayard Cousins. Reasons: height, eye color, and based on the limited photo we have of him, I don't think he looks like BCJD. BCJD looks like an individual, identifiable person in his sketch (unlike so many).
Charles Wallace was ruled out by his mother, but suspicions remain due to the way the newspaper article was written (IMO). She spent a long time with the body and seemingly couldn't decide one way or the other, finally settling on 'no'. The article kinda teases 'maybe yes, maybe no'. He's an interesting case, though.
We don't have an image of CW to compare, or any records for either him or BCJD.
In fact, I just took a quick twirl through Classmates.com to see if I could turn anything up. He doesn't appear in a search by name (edited to add: in Memphis schools), which doesn't mean he's not in a yearbook there.
However, Memphis has 500+ schools (colleges included) listed, and we have no idea which he attended, or when (or, come to think of it, if he even attended a school in Memphis). So theoretically we could slug through this (slowly), but no guarantee of any results. If there's a better resource for this kind of info, I'd love to hear about it!
