I just sort of been dipping in and out of this case, It's still a puzzle that you don't just vanish into thin air without leaving any tracks, the phone on the bench, The dog still hanging around on its own with its ball ?
Dog lovers know their dog will not just stay on its own ? They would follow you and pick up your scent to find you,
if it was planned to run away with somebody or go into hiding, then bikes are the best way of getting out of the park or woodlands or even use a boat, but also if somebody is using a decoy and trying to put people in the frame of the real crime, then close to home/work should be looked at and even from her past ? Somebody knows her and the dog, the dog would be going mental if a stranger was trying to hurt her,
if he's fell into the water, would it not be easy to see the struggle and marks of some sort in trying to get out
also, the ball if she was trying to retrieve from the water would be the last thing you think about if you're in the water and panicking, so how come the ball still had its ball ?
