DNA Analysis of Human Blood Recovered from Explosion Debris
A detailed study was initiated into natural gas migration in a residence and the effects of a natural gas explosion on both physical and biological trace evidence. Personnel from several Provincial and Federal agencies participated in this study 1. The biological portion consisted of two experiments: 1. To determine if a simulated homicide scene could be recreated from blood spatter evidence recovered from the explosion debris. 2. To determine the effects of a brief, but high temperature, natural gas explosion on the ability to obtain reliable DNA typing results from exposed bloodstains.
