Hello shepz,
I have to choose one thing?! Im finding working on active live search cases pretty interesting, seeing how the police gather conventional intelligence, and how I fit into that.
There was an interesting one the other day – a confession led to just a head being found in a drain. It has been there for some time and the water had bleached the bones (presumably of calcium) so the head itself was translucent, interesting if grim!

Hi Shepz
Getting involved in case work with the police or defence is always interesting. Seeing how science is put into action in the real world and then how the results of work that you may have been involved in can help resolve uncertainties in a criminal case is very rewarding.
The research work is also very interesting, there you have more time to cary out experiments and evaluate the results than perhaps in case work.

Hi shepz,
Every time that I attend a crash scene, it always fascinates me how the evidence that I collect at the scene, at the subsequent mechanical exam of the vehicles involved, the evidence at the post mortems and the forensic evidence that I collect and process all produce a picture of what happened. This is further enhanced when I get the calculator out and start to put speeds, timings, energy (delta v) and body kinematics into it. We have a simulation package, called Vista FX, in which we can download the survey data from our theodolites, put in vehicle size, model and masses, including occupant mass, and run a simulation of the collision dynamic. When that all works out, it is very satisfying. It is usuall a confirmation of what I have manually done and calculated.
It is what my role is all about – working out the causation factors of a collision (and it’s brilliant).
Thanks,
Mark.
