Pathfinder
(96815)
The technique of Electro Static Dust Print Lifting (ESL) at crime scenes dates
back to the early 1970’s. It is the ability to retrieve dust shoe marks from floors,
carpets, upholstery where photography and conventional adhesive lifting film would
be ineffective.
The benefits of footwear lifting at crime scenes is fast becoming identified
as the way forward especially as many criminals today are 'forensic aware' and
take precautions not to leave fingerprints or DNA at the scene. However they must
leave footprints which is where the CSI Pathfinder has proved most invaluable.
The problem with ESL machines currently on the market is that they are bulky,
costly, lack power when needed and often do not work because the connecting
probes or leads have been damaged by the previous user. they can also be very
dangerous to the operator because of the high voltage that is put out.
