I agree with your last sentence that is why I opened ...” I don’t suppose there will be many takers ..”@Popejohn3 Unfortunately these criminals already get reduced jail term sentences over time and so I would prefer that we use traditional means to find them and break through what is clearly some cover up and then hang them all out to dry.
Also in this particular case if the Perp(s) revealed where the body was they would likely have their DNA all over it and so would be convicted anyway.
We need to remember sometimes these things happen by accident !
By revealing the whereabouts you are showing ‘some’ copsssion towards the living .You only have to look at Peter and miss Cooper’s faces to see the anguish !
