That is complete rubbish. In Western Australia you dont serve your full sentence, you never do. You serve about 2/3rds maximum. He did not commit murder or rape and 7 years is an enormous sentence. It is more than likely he served 4 1/2 years, trust me, I know this. I could not think of one case where a maximum sentence has been enforced for anything other than the most violent of all crimes.
Morey is currently serving a large sentence for attempted murder. Parkie is claiming he was released and is now living in Bunbury, that means he didn't even serve his full sentence for that attempted murder sentence and only served about 2/3rds despite being a 'known' serial killer. I don't believe Parkie knows this though and is just making it up because we all know how difficult it is to find out if someone is still incarcerated and when their release date was so you could easily just make this up and no one would be able to dispute it. If Morey was let out though it would be in line with normal sentencing procedures.
You see the reason judges give out harsh maximums for crimes is so that they serve at least a good portion of the sentence. They are not required to serve a maximum under WA law. Only life imprisonment can have maximums and even then non parole periods are much lower even for the worst offenders.
I would say that if he was sentenced in 1991 he would have been locked up for some time prior to sentencing, that is time served, and then would have spent about 4-4.5 years in prison which would be in line with regular sentences even for a repeat offender. If he used a replica gun that would way in his favour. The law is the law its open for interpretation, it is not a set of rules.
Morey would have been out just in time for Karrakatta.
