Forensic chemistry

In 2013 Mick and Mairead Philpott were convicted with Paul Mosely of setting a fire at 18 Victory Road, Allenton, Derby. The fire killed all 6 childrei who were inside. With specific reference to this case, and using information readily obtainable from the media coverage of the trial, answer the following questions in relation to the fire scene evidence. In order to achieve the maximum marks for each part of the question, it will be necessary name the investigators & forensic scientists, and provide images or diagrams to support your answer. a) Describe the origin and cause of fire (scene images are expected here) b) What was the Philpotts' version of events and how did that differ from the prosecution allegations? c) What methods did the fire scene investigators use at the scene to determine what was used to start the fire? d) What other methods might they have used to help determine this? e) What samples would you have expected the investigators to take? Describe how they should have been packaged. 1) Describe, with the aid of diagrams the analytical technique by which the samples from the fire scene would have been analysed. g) What forensic evidence was found that linked the 3 suspects to the scene (which evidence linked which suspect?). h) Why do you think the 6 children were unable to escape from the fire, and is there any evidence to support the view that they tried to escape? There is court evidence from a fire investigator with regard to this.
