It is against the law to release information in an investigation.
It would be a crime to make evidence gathered during an investigation public.
The only time it is appropriate to release the evidence they collected is AT TRIAL.
So stop expecting anything to be made public until these people are arrested, charged, and tried.
And even then, the courts will redact lots of information to protect the victims.
If they are not brought to trial it will never be made public.
Everything must be done by the book for this to succeed.
Just be patient.
