Recent developments in DNA evidence
Marcus Smith & Monique Mann
ISSN: 1836-2206
Published: 16/11/2015
https://aic.gov.au/publications/tandi/tandi506

Foreword | In this paper, the authors describe recent developments in DNA technology. Key cases involving DNA evidence in Australia and overseas that occurred between 2003 and 2014 are used to illustrate the benefits and potential issues that can arise when new DNA techniques are applied to criminal investigations. Empirical data on the value of DNA evidence and DNA databases on investigative and court outcomes are outlined, demonstrating strong support for the value of DNA evidence to investigations and prosecutions.

The techniques and applications for DNA evidence described here, and future developments, clearly have important implications for policymakers, practitioners and legislators. Equally, the Australian criminal justice system will need to continue to adapt to accommodate new developments in this field.

Low copy number analysis

The amount of DNA left on an object after contact is influenced by a range of factors, such as the duration or type of contact. Low copy number (LCN) analysis involves the use of techniques to multiply small amounts of DNA, obtained from only a few cells. This technique was applied in the high-profile Murdoch v The Queen case in the NT Supreme Court (see Table 1). However, it has the potential to create erroneous results due to a high potential for contamination (Gans 2007; Lowe et al. 2003).

Killer breakthrough – the day DNA evidence first nailed a murderer
It’s 30 years since DNA fingerprinting was first used in a police investigation. The technique has since put millions of criminals behind bars – and it all began when one scientist stumbled on the idea in a failed experiment

An arrest of a 62yo man and extradition from Queensland GreyCrow

The murdered man has been missing for 17 years, his name is John Christianos.

https://www.9news.com.au/national/2...ristianos-body-found-in-wheelie-bin-melbourne
"A former Melbourne memorabilia dealer has admitted killing an "irrational and violent" graphic artist in 2001 before stashing the body in a wheelie bin.

John Spencer White pleaded guilty to manslaughter on Tuesday in Melbourne Magistrates Court after prosecutors downgraded the charge from murder.
The body of John Christianos, 40, was found in 2018 at a Oakleigh South storage facility as the business was being shut down and the owner was cleaning out the premises, the court was told."

Was thinking about tragic Judith Barsi the other day. It shows how much had changed by the 1980s that she was able to keep an "ethnic" surname in media. Had Judith been acting during Hollywood's Golden Era, the studio would have forced her to change her name to Margaret Williams or something else seen as "American".

Speaking of you tube I accidently found the you tube channel of Nixos Metaxas the first ever seial killer from Cyprus who confessed to murdering five women and two children after being arrested about two weeks ago.His last post on you tube was less than a month ago.Theres a few videos featuring chokers and wresting choke holds that he recently liked,he possibly knew his time was up when he liked them.A bit disturbing seeing as he strangled his victims .But nothing on the channel that isn't unusual for a proffesional type guy into photography and film making.If anything the guy seemed classy.

Might watch that later, thanks craigos

You think a thread would be good and have you checked out Documentary Heaven? There's some good ones in there too with ratings.

Propbably just general crime docuementaries, no need for it to be free even.

Oh wow, there's tonnes of docos on that site. I was spending way too much time searching netflix for good documentaries (crime ones are very hit and miss) and being the time poor/lazy person I am, was hoping people would do the leg work for me.
