The latest I've read is
"we're not interested in suitcase guy but WE WANT TO KNOW WHO HE IS"
paraphrased
but if you know cop talk. that translates to
He is a Suspect and he needs to turn himself in before we find him the Hard Way.
This guy is outstanding. He IS involved.
A well dressed guy with a suitcase in the main street of Wynarka would be equivalent to a float of strippers with a brass band accompaniment anywhere else.
Tiny Aussie towns like Wynarka roll along at a snails pace.
A strange face in town is fodder for gossip for WEEKS not days.
This guy was seen, with suitcase, and he didn't hitchhike to Wynarka, he drove.
So where is he now eh? South Australia is huge physically but barely settled. There simply aren't that many places for a well dressed guy to hide, even if he went bush he still would have to come to town for supplies.
If you study Australian Crime you will be aware just how often public help solves crimes. Milat was caught from public tips. People phone this stuff in all the time down here, especially when a child is involved.
Nope, suitcase guy is the one.
One thing occurs to me - maybe he was fatally ill at the time.
Maybe he removed the suitcase from his home so grieving relatives wouldn't find it after his death.
