ISIS SAR is the new ALSAR Unit covering Oxfordshire; I will write one day about the whole history of Oxfordshire Search & Rescue and ALSAR but suffice to say I’m pleased to now have an ALSAR Unit working in Oxfordshire (I just hope that Thames Valley Police will jump onboard soon too – but that’s another story, probably linked closely with the first!)

ISIS SAR have been asking me for a while to come up to Henley and do a training evening for them and I finally found a free date in the calendar last night. Following my ALSAR Presentation on Visualising Missing Person Behaviour Statistics it seemed sensible to carry on this with a training evening on missing person behaviour.

I started with a Powerpoint presentation, outlining some history, methodology etc. of missing person behaviour stats and how to calculate areas of circles and Probability Density. This was followed by a chance for them all to draw some circles based upon misper stats, work out their areas and probability density and colour in accordingly. We also looked at Track Offset data and Survivability Statistics.

The presentations are below; it must be noted here that all the figures were taken from Robert Koester’s Lost Person Behaviour book and credit must go to Robert and everyone else who contributed to these most important statistics. Let us hope they continue and are joined by many more…
