This is an interesting development. It is probably an important development. This is because the police force has stopped investigating this crime. Therefore in order to keep it moving forwards the involvement of a private investigator gives us hope that justice for Sage is possible and may be achieved.
A lot of people think that the police have not done enough. The perpetrator of the crime was in the house where Sage was tortured (I say and the evidence says but please see the updates as the investigator disagrees!). The pool of suspects is quite small. The public feels that it is possible to catch the criminal.
The police have refused to disclose what they have done which is a lack of transparency despite the fact that they are requesting help from the public.
There is a general dissatisfaction with the police force and this development will be welcome.
