According to the national fingerprint notes, which are used to train UK (and some international) forces, these are the accepted firsts:
First Evidence of Plantar Marks
The first time plantar (foot) identification evidence was given was at Aberdeen Sheriff Court on 17th February 1953. James Walker Adams was charged with burglary after his plantar impressions were found at the scene. Detective Superintendent Maclean of the Glasgow Fingerprint Bureau gave evidence of identity and Adams was found guilty.
On 1st May 1956, Detective Superintendent Holton from NSY gave the first plantar evidence in England at Hastings Magistrates Court against Sydney Malkin whose footprints had been found at the point of entry. At the trial the Judge, Mr Justice Gorman, in summing up said there was no evidence to show that plantar evidence was as competent as fingerprint evidence. However, the jury returned a guilty verdict and Malkin was sentenced to be `Bound Over' for 3 years.
First Evidence of Toe Prints 1959
The first time evidence of toe print identification was given in England was at Cheltenham Magistrates Court on 20th October 1959. Benedict Quilkin was accused of breaking into a sweet shop in Cheltenham where a toe mark was found on broken glass. Evidence of identity was given by Detective Chief Inspector Hurford of the South Western Fingerprint Bureau and Quilkin was sentenced to two years imprisonment.
I am interested to find out more about the Quilkin case due to it being its 50th anniversary, so if anyone has further information I would be very grateful.
Hope this clears things up, but it looks as though there could be some contention in this one!
