ok after this I will not harp on about the phone-ever, ever, again. After reading some posts and much reflection, IMHO, the phone is key. And I am not of the opinion that it would clear GBC. The direction of the QPS leads one to assume that this was NOT a random attack-even said so themselves. So, IF ABC knew her attacker, and if she died at home, the phone was more than likely ditched afterwards (thanks Thinking & itsthevibe) to make it look as though she had gone for a walk. OR...ABC died at the park (main suspect=gbc), and phone ditched there anyway....and built the 'gone for a walk story' afterwards. Either way, IF the main perp contacted 3rd/4th party?....I would guess that it was done using ABC's phone. Sure as sugar not likely on perp's phone. IMO that is why qps have been busting their gut to try and find it...they are still looking for it, after ABC has been found...
