Notable Cases

  • R v CHILTON (2014)

Nicola established the size of the relevant cells and determined whether the telephone movement supported the defence case statement.


  • R v TOMASA & Others (Cayman Islands 2013) 

Established the movement of the telephones before and after the bank robbery and analysed calling patterns, in order to establish whether the calling behaviour was unusual.



Conspiracy to supply Class A drugs. Analysed the telephones attribution and movement.

  • R v NOWAK (2013) - Murder of Catherine Wells. 

Compared the calls and movements of a ‘clean’ and ‘dirty’ telephone, pre and post the murder, in order to establish whether Mr Nowak could be the user of the telephone associated with the crime.


  • R v Daniel D’AGE (2012) - Conspiracy to supply Class A drugs

Nicola analysed the calling patterns and contacts between the telephones allegedly attributed to dealing, together with 25 other telephones of interest. The phone movement and frequently used cells were also analysed, in order to establish the usage of the ‘dirty’ phones, compared to the ‘clean’ phones.


  • R v FROST & ISLE (2011) - Series of 20 robberies of high value agricultural equipment. 

Nicola analysed 11 telephones, showing the movement of each around the time of the robberies and comparing the findings with the serving cells at the locations of interest. 


  • R v D’AGUAIR (2010) - Murder.

Nicola commented on the movement and likely whereabouts of the telephone around the time of the murder.


“Ms Haigh is extremely competent, has considerable knowledge of her field of expertise and has considerable skills in both interpreting material presented to her and in producing excellent materials for use in trials”.

“She is very professional in her approach to all issues that arise and is, in my view, one of the best experts in this field. I have had no hesitation in recommending her to other counsel.  One of the things that has most impressed me is that she is able to get fully prepared for trials with very little lead time (always a problem as defence funding often comes late) and yet the quality of her work and thoroughness outshines prosecution experts, who have had considerably more time on the case and better funding!”
