What needs to be clarified
Review the documentary basis for the donor count and statistical evaluation, including alternative assumptions and the report's stated limitations.
Materials to prepare
- Full report with locus tables and competing propositions
- Electropherograms and available electronic data for the trace, controls and reference samples
- Interpretation thresholds, model description and calculation settings
What to compare
Check tables against electropherograms, mixture components and possible allele drop-out or drop-in. Compare thresholds, controls and the donor-count rationale. Identify which propositions the likelihood ratio addresses and whether justified alternative conditions change the evaluation.
Possible outcome of the analysis
A review may list testable assumptions, gaps and calculation questions; sufficient data may permit an assessment of whether the mixture interpretation is reproducible.
Limits of the conclusions
Document review does not replace laboratory testing. Statistical support for a donor proposition alone cannot establish when or how DNA transferred or the circumstances of contact.
