LE is often very closed-mouthed about their investigations. Actually, not just often...always. Every police agency I've ever seen is tightlipped about their cases, though I will say the UTPD was particularly so, with no press conferences. They obviously were very busy.
Please never assume that while investigating a homicide and keeping their mouths shut (especially a homicide of a child) that LE has forgotten a case or is not giving the case priority, because they aren't talking about it. A homicide is their #1 priority, especially when the perp is still on the loose. They can't put everyone on one case as they still need to attend to other cases and community needs, but rest assured, LE is "on" it even if you can't see it.
To whom was this directed? Who do you believe was 'assuming'?
