Expert Witness Service - Screen4

Expert Witness Service

What does this involve?

Toxicology is widely called upon in the investigation of a wide range of crimes including:

  • alleged sexual assaults involving drugs
  • driving whilst impaired through drugs,
  • driving with excess of alcohol,
  • possession of drugs with intent to supply.

Cansford our Laboratory Service provider can assess whether the interpretation already provided is a balanced assessment of the evidence and advise on avenues that have not been pursued that might be of benefit to the defence or if there are any aspects of the analysis that give cause for doubt in the case for the prosecution.
