I wonder how the police placed the murder in Wallaroo - they seemed quite specific re times. How far is Hall as far as clicks do you think? I only ask because I was talking to a friend who is a police officer and specialises in covert tracing, phone pings and the like the other day, (he refers to it as secret squirrel stuff - he won't discuss cases or specifics, obviously) and he said they are quite inaccurate as far as being able to pinpoint locations, and what they are looking for could be in quite a large area as to where the pings are picked up from.
I forgot to mention your other post ... yes, they are very much known to attach themselves to single mothers. They tend to show themselves to be great for their kids, etc, and being single mothers, they are usually vulnerable and don't have the normal support network such as brothers, fathers, uncles, etc, who can not only help out, but have an antenna for those type of men who prey on single mother's children.
