just reading back on an article i found:
http://www.canberratimes.com.au/nat...re-killings-20120928-26qql.html#ixzz27nvxaLDA
this is the one where they talk about Crew four (The dogs) moving in on investigation on Sunday and serveillance on AB. "Surveillance police observed him behave as if an average guy from the suburbs, heading to work and following his normal routine
The way I have read it, they had there named man as soon as they viewed cctv. Was this on sat/sun. As they observed him heading to work/following his normal routine. that sounds like thats a few days, to claim a "routine" was folllowed, before the arrest was made on WEdnesday. Hence why they knew JM wasnt alive as they were following him from the moment they watched the cctv.
not sure whether this was discussed, but i just found it interesting they had there man within a day or so.
