23 A major issue before the jury at the trial was whether, indeed, the prosecution had established beyond reasonable doubt that Sturgeon was the driver of the Mitsubishi Pajero at the time the group of pedestrians was run down and the two young men named in the indictment were injured. On this issue the accused, through counsel, submitted that although the DNA/blood evidence, if accepted, would show that his blood was found in the vehicle, it did not explain how the blood came to be there and, in particular, did not prove that it was him who was driving the vehicle at the time the two young men were injured. In support of this contention, counsel for Mr Sturgeon pointed out that the evidence demonstrated that, after the incident on Scarborough Beach Road happened, and much later on the morning of 2 October 2004, a third person was known to have been driving the vehicle for a short period but that when it was examined forensically and tested for traces of DNA no samples of this third person's DNA were found nor, for that matter, were samples of DNA found from anyone but the accused and the vehicle's owner. This, so the argument ran, meant that it was possible for some unknown person to have used the vehicle and not left any trace of his presence.
