Forensic pathology in New Zealand - Forensic Scientist
Mar 11, 2016 •
In an article on 09 March 2016, Justice Brewer was described as saying that if he’s forced to adjourn a murder trial involving a Taupo toddler, he will be calling for an inquiry into New Zealand’s forensic and pathology system. This was in response to a defence lawyer indicating that he had had difficulty instructing an independent forensic pathologist to review the findings of the Crown-instructed expert in addition to Justice Brewer’s previous experience of similar issues in other cases. I was called by a journalist from the NZ Herald the same day and asked for comments (“Forensic shortage irks judge”). The story indicates that I am a forensic pathologist. I am not, and I have asked the Herald to correct the error. The main point of this post is to indicate that New Zealand is deplete … Read More

Forensic Hair Analysis – does it get to the root of the problem? - Forensic Scientist
Sep 17, 2015 •
Hair analysis is often referred to as hair follicle testing. It is commonly used in Family court matters to assess whether or not parents or caregivers who want access to children are drug-free. The process involves collection of a sample of hair (usually from the crown of the head but other areas are possible) by a trained hair sample collector and then analysing the hair for the presence of drugs. Hair analysis is often claimed to be the perfect solution to the question of determining historic drug use or abuse. Segmental analysis is said to determine use over a period of time – on average for adults a centimetre of hair is said to represent a month’s growth so analysing a strand of hair that is 10 centimetres long would reflect the subject’s use of drugs over the ten months … Read More
Of the FBI and ESR: what can we expect forensic science to deliver? - Forensic Scientist
May 12, 2015 •
I haven’t written a blog post for a loooong time. That’s because in the last year or so I have written another book (Forensic Science and the law: a Guide for Police, Lawyers and Expert Witnesses – the first book of its kind in New Zealand) and have been involved in some high-profile cases including (read more)
Prosecuting sexual assault cases – new approach? - Forensic Scientist
Feb 03, 2015 •
When Judith Collins was Minister for Justice she suspended Law Commission work on alternative models for prosecuting criminal cases. The Law Commission had originally been asked to consider alternative models by the earlier Justice Minister, Simon Power. A paper was released in February 2012 entitled “Alternative Pre-trial and Trial Processes: Possible Reforms” – so a (read more)
Of zombies and children - Forensic Scientist
Jan 03, 2015 •
“ ’Scuse me, but do dead bodies really look like zombies?” As questions go at the end of a presentation, this one took me by surprise – but I guess it shouldn’t have done so, given that I was speaking to about 150 primary, intermediate and high school gifted children. With hindsight, it’s exactly what (read more)
The CSI effect – it’s still going…but changing shape? - Forensic Scientist
Dec 17, 2013 •
Here is a link to an article on Stuff.co.nz today that deals with the CSI effect: TV shows having an influence on juries. As you will see, I added my two pennarth to it. In my experience over the last 12 months, as a phenomenon the CSI effect raises less questions at presentations and lectures (read more)
Expert evidence: can we learn from others? - Forensic Scientist
Dec 17, 2013 •
One of the hardest things to do in life seems to be to learn from the mistakes of others. For example, when learning to drive (“mirror, signal, manoeuvre” has been devised for good reason, not, as young male relatives seems to think, just so older people can tell younger people what to do and then (read more)
What is a standard alcoholic drink? - Forensic Scientist
Nov 06, 2013 •
What IS a standard alcoholic drink? It’s a nightmare, that’s what it is. As a forensic alcohol toxicologist, the concept of a standard drink is somewhat arbitrary and inconsistent because the people drinking them differ in physical stature and biological processing ability so the alcohol in a standard drink contributes a different amount to people (read more)
Don’t forget: breath alcohol levels continue to rise after you stop drinking! - Forensic Scientist
Nov 06, 2013 •
I have just been watching Campbell Live where the presenters had a two-hour lunch with alcoholic drinks and then tested themselves with a breath alcohol screening device to see how they felt to drive compared with what alcohol they had actually consumed. This is all as a result of the government’s (good, in my opinion) (read more)
Children and mud: mutually exclusive?! - Forensic Scientist
Nov 05, 2013 •
At risk of sounding like an old person, I still have to ask at what point did children become allergic to outdoor entertainment involving mud, rain and a stick? I ask this seemingly inane question as the result of a school trip to the local beach on which I was a parent supervisor recently. We (read more)
