Ok, so for arguments sake..hypothetically speaking, if the pings were located to that specific area, it might stand to reason that this was the area where her phone was left/ditched. If Allison died at home (pure spec), why stop and ditch a phone there. Would be easier to do this if this area (park) is where her death took place. Hence the 'hot zone' and intense searches in this area, the screams may also be evidence of this...I had a blazing row with my ex-fiance many years ago. It was dark, and late, and I stormed off to get away. I didn't care about how I looked or what I had on the next day-way too emotional and upset to care. My relationship was breaking down. This was my neighbourhood, lived there many years...not that I felt safe so much as I didn't feel unsafe. It is possible, I believe, that Allison may have gone for a walk. It is also possible that she died there at the park. What's this got to do with the price of petrol? the difference between "Judge, I didn't mean it, it was an accident" well actually, you did meant it...IMHO
