“
Ennis Lt. Michael Hopson told NBC News Monday the investigation is ongoing and no foul play is suspected. Investigators have not ruled out any suspects, Hopson said.”
'We Just Miss Her So Much': Vigil Held for Missing Ennis Mother Emily Wade
The wording here makes me think that LE does in fact suspect foul play and has identified a suspect, but they are being tight-lipped so as to not alert him/her.
I can think of at least three case off the top of my head where throughout the investigation LE maintained “so-and-so has been cleared” or “S/he isn’t a suspect,” only to say once an arrest was made that they suspected the individual all along.
I wish I could be more of a help, but after all this time, I still can’t come up with a viable theory as to what may have happened or where Emily might be.
