I will talk next week (Tuesday, 2 December) about difficulties of interpreting DNA evidence, illustrated by the case of Tamara Wolvers. Tamara was a young lady, murdered in her parent’s house in Alpen on the Rijn, in 2006. Police investigations led quite rapidly to one particular suspect “Jaco G”. Possibly the main (or at least, “hardest”) piece of evidence was a mixed DNA profile in which the DNA of at least two persons could be found: the victim and (presumably) the perpetrator and perhaps a third person. The analysis of mixed DNA profiles is very tricky, especially when the mixture is “unbalanced”.
I hope to find some scientific literature on forensic DNA which could be accessible to you and relevant to the case, as well as some more or less scientific literature pertaining to the case itself. So: “watch this space”.
My report to the court of appeal on the DNA evidence in this case:
