Question 3

Is it possible to determine on the basis of these photographs whether Person A and Person B are one and the same person or whether they are different persons?

Answer

It is impossible to answer this question. There is a lack of detail in the facial features of Person B for a reliable comparison. The upper part of Person B's face is hidden by his hat, and the lower part by facial hair. There are certain similarities, for example, in the general shape of the face and the general shape of the nose. However, this kind of similarity can be observed in a significant number of persons.

Question 4

Is it reasonable to use only photographs N7-GO and N8-GO for identification with a positive result?

Answer

No, this would be both unreasonable and unreliable from a forensic point of view. There is an insufficient amount of detail in the facial features here and therefore a clearly insufficient number of measurements can be carried out.

APPENDIX A PHOTOGRAMMETRY RESULTS

Photographs N3-GO and N8-GO were used. They were taken at different scales. However, if ratios of values (distances) are used, the need for rescaling can be avoided. In each case, 10 measurements of each distance were performed, then, in order to reduce measurement errors, the average value of the results of these measurements was used.

Results

• Person A
• Person B
