Abstract

- Urine can be a potential important source of evidence when occurring at crime scenes. In case of outdoor scenes including snow a yellow colour could indicate the existence of human urine. In an effort to be able to investigate urine as a crime scene sample we have evaluated protocols for analysing DNA from urine in snow. Two different tests were performed with a smaller and a larger volume of urine dispensed on snow. The tubes were put into a freezer to mimic winter conditions. A Urine Preservative was added to some of the samples. DNA profiles were compared between samples extracted using a Urine DNA Isolation Kit and samples extracted with a Chelex-based method. In addition, a test was performed with the aim to mimic a potential crime scene. With a smaller volume of urine the best quality DNA profiles were obtained using the Urine DNA Isolation Kit without the Urine Preservative. When a larger volume of urine was handled and in the crime scene setup, there were no clear difference between the two extraction methods. Instead, the variation observed was between individuals.
