Bumblebee technique may help catch serial killersJuly 30th, 2008 - 3:13 pm ICT by ANI
Washington , July 30 (ANI): Catching serial killers may now be just a few fingertips away for police, thanks to a new technique, called Geographic profiling (GP), which scientists are testing on bumblebees.
Scientists from Queen Mary’’s School of Biological and Chemical Sciences are helping to perfect this criminology technique to prioritise lists of suspects in investigations of serial crimes. It uses the sites of a serial killer’’s crimes to predict where the killer is most likely to live.
Dr Nigel Raine, and Dr Steve Le Comber, from Queen Mary’’s School of Biological and Chemical Sciences, collaborated with Kim Rossmo, the former detective who invented the technique, to use it to look at patterns of foraging in bees.
They found that they could use GP to distinguish between different types of foraging behaviour by observing bees foraging in the lab, combined with computer model simulations.
GP takes into account two factors: the fact that most serial crimes happen close to the killer’’s home; and that the killer’’s home is surrounded by a ”buffer zone” - an area where the opportunity to commit a crime is comparatively low.
Keeping in mind these two parameters, criminologists created a geoprofile, which shows the areas where the killer is most likely to live. The more accurate the GP model the more precise the geoprofile and the quicker the police can track down the killer.
“GP is interesting to biologists because it can tell us which strategies animals use when foraging. The approach works well for very different animals: from bees and bats to great white sharks, explained Raine.
The findings may also help criminologists, as the experiments can be used to test the GP technique - something which is impossible to do with criminals, for obvious reasons.
The results of the lab experiments allow the GP criminologists to perfect their technique, and predict the serial killer’’s location with more accuracy.
This bee study is the first time that the assumptions of GP technique have been tested using an experiment. This study suggests that bees could create their own ”buffer zone” around the hive where they don”t forage, to reduce the risk of predators and parasites locating their nest.
Results indicated that GP can be used to find the entrance to a bee hive, from observing the locations of the flowers that bees visit. This has implications for bee conservation.
In future, GP could be applied to help locate bee nests, or areas of potential nesting habitat a valuable tool for reversing the numbers of rare or endangered bumblebee species.
The study is published in the Journal of the Royal Society Interface. (ANI)
