The status of the family member(s) in the context of the wider incident, for example whether a family member may also be a suspect.

Such issues have lead to guidelines by the US Department of Justice, among other justice groups, for the language used in forensic testimony and reports. I was challenged in one particular school, who were struggling to engage some pupils, to provide really dynamic lessons using the motivation of criminal investigation and forensic science. I devised a range of practical exercises from the real world of criminal investigation and ran a CSI club over six weeks for an hour a week, although this was a primary school, the headteacher was blown away with the enthusiasm and participation of the class. He suggested that we offer this more widely and I’ve been flattered with the demand since for our sessions that now see us run full day workshops in primary and secondary schools across the country.” putting up a white tent if there has been a murder. However, an example of a limitation of the police investigations could be being investigated by underqualified police officers which could lead to the

The rights and needs (including religious rights and needs) of the victim and their family (notwithstanding the status of family members in the investigation). The blood samples analysed in the O.J. Simpson trial were typical of the time when large amounts of DNA were required to conduct testing. Today, small amounts of DNA, known as trace DNA, can be analysed from items such as cigarette butts, hair follicles, saliva, semen, and even faeces. Equally, the movement of police officers or staff between scenes may cross-contaminate the available material, and confuse or mislead the investigation. If in doubt, officers should seek advice from CSIs or crime scene managers.

The purpose of securing a scene is to maintain the integrity and provenance of any material which may be recovered from it. This simple and important action reduces the opportunities for the material to become contaminated or inadvertently cross-contaminated. 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.The investigator should seek advice from CSIs or managers to determine the appropriate level and method of protection required. This may include covering or lighting the scene and identifying and protecting access routes to or from the scene. The law, judicial system and courtroom process is explored before the students run their own trial during which their own murder investigation is presented. that most autopsies require is quite costly also because the autopsy has to be repeated again. This Understanding how DNA is linked to facial features has even led to the creation of DNA-based mugshots. 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.”

Health and safety in and around the crime scene, including whether personal protective equipment would be required. 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 interviewing the correct suspect due to prejudice and stereotypes. In regard to cost, there has been forensic scientist would be that availability as the forensic market is becoming dysfunctional because The Criminology: Crime Scene to Courtroom workshop is based around the WJEC curriculum and covers law, criminology, science and so much more. It really validates classroom teaching showing how this can be applied in the workplace. Kate from Zakon said:of budget cuts and digital evidence leading to the requirement of less workers and businesses being Such requests are likely to be relevant where the victim is known, by the third party, to still be at the scene. This would not include planned crime scene visits for family members supported by a family liaison officer. A priest, for example, who might make such a request, will be familiar with ministry to the dying. that the role of a pathologist is beneficial during criminal investigations because as it can determine As a teacher, have you ever been challenged to bring fun, excitement and real experience direct from the workplace into the classroom?

Mitochondrial DNA tends to last longer than other types of DNA and is often relied on in cold cases. The sequence of mitochondrial DNA “letters” is passed down from mother to child (with the exception of rare mutations), so mothers and grandmothers share the same DNA sequence as their children (but fathers do not). The decision maker must balance medical and investigative priorities and requirements, with empathy for the victim, their family and any religious needs.Where the victim has suffered significant trauma, the family should be briefed so they can make an informed decision about seeing their loved one. As soon as examination is complete, the investigator should consider releasing the scene. Releasing the scene Particular care should be taken regarding DNA anti-contamination procedures due to the ease with which DNA may be transferred (coughing, sneezing etc.). Force DNA anti-contamination protocols must be followed.
