“This is the basis of all forensic examination of crime scenes. 1. Police Cordon – Cordons are put in place to ensure that vital evidence isn’t lost by allowing everyone in to trample their way through the scene. A log is kept detailing everyone who enters, why they are there and the date and times they arrive and leave. 2. CSI – Crime Scene Investigators attend crime scenes to examine them for evidence to help prove or disprove someone’s involvement in the incident. 3. Witnesses – Police will ask as many people as possible for their version of events to help get a full picture of what happened. 4. Victims – A lot can be determined from a victim of crime. From their statements detailing their account of what took place and from evidence left on themselves or their clothing. 5. Police officers – often present at crime scenes to take statements, to log exhibits, to man the cordon to record anyone entering and to prevent entry from others. 6. Photographers – Attend to film and photograph serious crime scenes. Photographs capture exactly what is present and can serve as a visual representation to show to others who were unable to see the scene in person. 7. Suspects – Sometimes suspects are found at crime scenes. It could be that they have reported the crime themselves and are pretending to be a victim might or that they are still on scene when police arrive. Like victims, suspects will give us their version of what has happened and may carry a whole host of evidence on their person. Not every suspect is guilty of the crime they are thought to be linked to so it is vital to get as much information from them as it might rule them out of the investigation or put them firmly in the middle of it. 8. CSI tape – this is to mark the cordon and has a knack of bringing everyone in the vicinity to the area as if it were a magnet. 9. Fingerprints – my favourite! I could go on about these for hours but suffice it to say that they remain the only positive means of identification. Yes, DNA is fabulous, but identical twins will have identical DNA whereas no 2 people, even identical twins, will have the same fingerprints. 10. Shoemarks – Until we can fly, we will always leave shoe marks wherever we tread. There are many ways of recovering shoe marks depending upon the surface they are on. 11. Hairs – We regularly inadvertently leave our hair behind throughout the day without event noticing. It contains DNA which can identify who it has come from. 12. Fibres – much like hair, our clothes will shed fibres and as they encounter other materials. Fibres will be transferred from one to another (remember what Locard said?) We recover fibres by plucking, taping, brushing, sweeping and forensic scientist inspect them microscopically to look for matches. 13. Indented writing – this is cool. Remember as a kid you’d crayon over a page in a notepad to see what had been written on the previous page? A more sophisticated method is used to achieve the same result without damaging the exhibit. 14. Blood – Blood at a scene can identify both victims and culprits through DNA and can determine what took place by the blood spatter patterns left behind. 15. Semen – Often found on clothing (victim and suspect), skin, furniture, bedding, condoms etc. Contains DNA so can determine who it has come from. 16. Weapons – when we think of weapons we often go straight to guns and knives, or of course the obligatory candlestick in the library. Some weapons are taken intentionally to a scene and some are items picked up and used spontaneously. Whatever has been used in a physical attack needs to be found and isn’t always at the crime scene itself. Officers spread the search far and wide to locate weapons if necessary.” --- Send in a voice message: https://anchor.fm/antonio-myers4/message Support this podcast: https://anchor.fm/antonio-myers4/support
