This day is very close to Simon’s heart as it was his daughter Isabella’s school where this initiative started and she is still the face of the Police and Crime Scene Science Workshop which can be seen here and this continues to grow in popularity. study is an example of cross contamination. In conclusion, I believe that the use of a forensic scientist It is difficult for people to comprehend probabilities like one in a quadrillion, and the presentation of such numbers in court can become prejudicial.Once investigators have identified a scene or multiple scenes, they should make an initial assessment of its potential to provide material. The assessment and subsequent formulation of a scene strategy (which should include necessary resource allocation) should have due regard to forensic strategy considerations. Undue delay or failure to consider forensic issues at this stage may lead to valuable material being contaminated, overlooked or lost. and analyse the DNA found at the scene of the crime, which is particular and specific to one person,

In major or complex scenes where several crime scene investigators are required, a crime scene manager should play an active role in managing all aspects of the scene examination. ensuring that persons entering the scene are wearing suitable protective clothing to prevent contamination of the scene, and to ensure that they are protected from any hazards present The Y chromosome is present only in males and is passed from father to son. This makes Y chromosome STR markers a useful tool in situations such as sexual assault cases where male and female DNA samples might be mixed and the male suspect’s identity needs to be established. interest of providing accurate information that may help to acquit or to convict a person of a crime. of budget cuts and digital evidence leading to the requirement of less workers and businesses beingHealth and safety in and around the crime scene, including whether personal protective equipment would be required. The crime scene can present itself in a number of ways and may not be immediately obvious to the investigator or initial attending officer. There may also be multiple crime scenes which relate to the offence. The extent to which investigators are responsible for managing a crime scene and developing crime scene strategies is influenced by the complexity or seriousness of the investigation and local force policy. When gathering material, investigators should liaise with CSIs and managers to ensure that they use the most appropriate method for examining the scene. Identifying scenes perpetrators being wrongfully free to walk the streets without a conviction. In conclusion, I believe

It was great to see the links between what they learn at school and where it can take them, for some of our budding scientists in particular. Phil (from Zakon) commanded the children’s attention for extended periods of time, I take my hat off!” A thorough examination of the scene is essential. As there is usually only one chance to do this, scene examination should not be made in haste unless a delay would result in the decomposition of evidence. Relevant experts should be consulted, where necessary, before commencing the examination. This is possible because of the invention of a method in the 1980s called the polymerase chain reaction or “ PCR”, which allows an individual strand of DNA to be replicated many times. This creates thousands of copies until there is enough DNA to conduct tests. Analysis beginsscene investigators whose role is to preserve and protect crime scenes, record crime scenes, capture The school days are by far my favourite events to run, to think I started this day as a favour in my daughters school and now my small team are inspiring young people across the country fills me with pride every single day.” Understanding how DNA is linked to facial features has even led to the creation of DNA-based mugshots.
