When the Public Affairs person for the DPD comes out and says something to the effect, 'if anyone has any information about this case, please call....' , I personally think it's more of a pro forma statement, used anytime there has not been an arrest in a case. JMO.
This may be naive and just trusting on my part, but, that said, IMO DPD doesn't need the public's help in finding Janet's murderer. All along they have said the crime was not random and that the public has nothing to fear. I still maintain this means one thing and one thing only - they have a suspect, they know who murdered Janet, and are diligently putting the pieces together for an arrest. I really do believe it's that simple, but again, that's just my opinion.
Hearing nothing from them actually doesn't bother me. I just have to believe it's for a good reason.
As far as a new detective - how can that be bad really? Perhaps this person has more homicide experience. Perhaps it was simply a matter of shifting around some cases. IF a new detective is not as forthcoming with family, etc., if true, then that could simply be a matter of personality as well. Who knows. But a fresh set of eyes, an objective opinion, etc., these are good things IMO....
Again, personally anyway, I'm just not concerned about a lack of public info from DPD. I think a puzzle is being put together, plain and simple. And a puzzle often takes time...to make sure each piece is in it's proper place. And when it's all done, the puzzle's complete - and an arrest will result. When? Today, tomorrow, next week, next month - other than our frustrations, it's not important. At the end of the day what matters is one thing - that there IS an arrest.
And an arrest is only important if it's a solid case with solid evidence - that ultimately leads to a conviction, plain and simple.
