In November 2007 in Perugia, Italy a British foreign exchange student named Meredith Kercher was found stabbed to death in a cottage she shared withe three other roommates. Soon after the homicide was discovered an American exchange student was arrested and charged with the murder. Amanda Knox was one of the victim's roommates. Amanda claimed she was not at home when the crime occurred and returned to the apartment with her boyfriend and another roommate.The door to Meredith's room was locked and the returning party found that odd. They could not get her to open the door. They were concerned so they called the police. Amanda and the others called the police. The Italian Postal Service arrived instead of the Italian military police. Postal service employees do respond to misdemeanor crimes in Italy but have no experience in violent crimes. After breaking down the door, they discovered the victim dead in her bedroom. Many people entered the room that day. Several people had tried to open the bedroom door. The two Postal officers entered the room and were wearing their regular uniforms. Video taken at the crime scene showed that items and furniture had been shoved and moved around the room. Blood was found in the bedroom and in the shared bathroom. No post mortem temperature reading was taken from the body at the time of discovery. Information from: http://inpublicsafety.com/2014/02/veteran-forensic-scientist-examines-negligence-in-the-collection-of-evidence-against-amanda-knox/ 1. List one mistake made by the Italian Police Department initially at the crime scene. 2. List at least two types of evidence that could have been collected from this scene. 3. Explain the problem with the chain of custody in this case. 4. List the steps that should have been taken in the investigation of this crime scene.
1) The Italian Police Department did not secure the scene. 2) A sample of the blood that was found could have been taken to biology/DNA to see if it was the victim's DNA or someone else's DNA. Another thing that could have been collected was fingerprints. If the suspect touched the door knob it is possible that they could have lifted a fingerprint. However, since so many people touched it the evidence was compromised. 3) There really was no chain of custody. Evidence was not collected properly and certainly the chain of custody was not followed to ensure validity of the evidence. 4) The steps that should have been taken were... 1) Protect and Secure 2) Observe and Document 3) Photograph/Video 4) Sketch the Scene 5) Search the Scene 6) Package the Evidence

Based on what you know about the role of a CSI, which sentence(s) in the episode description falsely describes how CSI contribute to the investigation of a crime? MORE THAN ONE ANSWER MAY BE CHOSEN. Season 14: Episode 1 - The Devil and D.B. Russell. After learning that CSI Morgan and Ellie Brass have both been taken captive by their still unknown murder suspect, the CSIs race to piece the clues together and solve the case before it's too late. The killer, using engravings from Dante's Divine Comedy as inspiration, leaves two more bodies for the team to find, then kills their chief suspect in a fiery explosion. With only two of the Nine Circles left, the CSIs know that Morgan and Ellie will be the killer's next victims. The CSI supervisor, Russell, makes a break in the case when he is examining the body of a victim to determine the cause of death and solves an anagram that was engraved under a victim's skin, leading them to Jake and Matthew Chapman. As the CSIs race for the Chapman hideout, Morgan and Ellie manage to escape, killing Matthew in the process. However, Ellie surprises Morgan and shoots her, then lies to the cops while Morgan is unconscious in surgery. Later, Ellie kills her mother Nancy, then turns the gun on her father, Brass. Fortunately, the CSIs uncover that she was the one responsible for the murders and arrive in time to subdue and arrest Ellie.
