This week’s assignment involves testifying in court. We will try to understand some of the difficulties and moral dilemmas involved with testifying about forensic evidence. Read about the following case, and then follow the directions to complete the assignment on a Discussion Board. Miley Cyrus has been murdered! Her body was found wrapped in plastic at a rest area on I-20 near Atlanta. Police suspect and arrest Kim Kardashian. The two had been seen arguing at Tal Cel Con (Talentless Celebrity Convention or TCC) before the murder. Police suspect that Miley confronted Kim at her hotel room, where there was a struggle and murder. Their theory is that Kim then wrapped Miley in plastic, loaded her into a Lexus, and dropped her off at the rest area. However, if this is what happened, it was a very clean crime. Police have difficulty finding much evidence. However, they do find many fibers on the plastic that Miley was found in. You are a forensic scientist working in the Trace section of the Georgia Bureau of Investigation. Police submit fibers found on the plastic and fibers taken from the carpet in the trunk of Kim’s Lexus. You compare the colors – they are both grey. You compare refractive indexes – they both are 0.85. You run a FT-IR on both samples – they are both the same type of nylon. After looking up information about the Lexus, you find that the carpet is Antron Lumena® made by DuPont. After cooperation with DuPont, you determine that the fibers found on Miley Cyrus’s body are also Antron Lumena fibers. Dupont says they have made this fiber since 2004. It can be found in many carpets, and in carpets found in nearly all recent (since 2004) Lexus cars and SUVs, all recent Infiniti cars and SUVs, about ½ of recent Cadillacs and BMWs, and a portion of the 2006 Buick LaCrosse. You are called to the stand. The lawyer asks you: “Did the fiber found on Miley Cyrus’s body come from Kim Kardashian’s car?” “You’re the expert. In your opinion, how likely is it that the fiber came from Kim Kardashian’s car?” “Is there anything else you want to say to the jury about the fiber?
