Recommended: Evidence at the crime scene

What other evidence located in the grave can be analysed further, and how?
Other evidence located within the grave consisted of a generic watch, two cigarette butts, a button, a washer and a shell casing. All of these could be analysed for finger prints and DNA. The cigarette butts would also show a serial number indicating the brand (shown in Figure 3), which can be useful if it is found a victim or offender smokes a particular type of cigarette. Figure 3
The button and watch may be identified as belonging to a victim or offender. A witness may recognize the button as belonging to a specific individual’s clothing.
The shell casing may also be used to help distinguish the type of bullet and gun used. Both the button and the shell casing could have DNA and fingerprint evidence.
Is there other information you can gain from the evidence?
The brand of the cigarette butt is legible, which, following identification of the victim or perpetrator, can be used as an identifying feature as evidence in court. The brand of the other cigarette butt is unknown, but could identify an individual who rolls their own. Further, DNA and finger prints could be traced on both.

The shell casing could be matched to a particular model of gun, further DNA and …show more content…

There is potential DNA or a finger print may be found, but as both types of evidence can be wiped off or damaged, this may not be a guaranteed method. If a victim or perpetrator is identified, there is a possibility the watch may be recognized as being owned by one of them, however, because of the nonspecific state, this would be supplementary evidence and not an identifying factor. In the case of the button, it is possible a search of the victim or perpetrator’s (when identified) residence could result in the discovery of the item of clothing from which the button

  • Max Powers Case Study

    1692 Words  | 4 Pages

    The first piece of evidence that led to this theory was ice tray that was located at the crime scene. Due to the chromatography paper which was tested in Forensic Lab 7, it was revealed that the ice tray was poisoned by the one and only Beverly Hilis. In the Forensic Report it states, “The ph in the ice water was 9”(Forensic Report). This is significant, because this was the exact same ice tray Max used in his drink. The only person that was able to poison Max at the crime scene was Beverly. This is important, given the fact that the chromatography tests results showed that the ice tray was poisoned, Beverly could have made the poison because she is use to performing experimental things especially being a Chemist. Another piece of evidence that led to suspicion was Dez’s towel which was found at the crime scene. In the Preliminary Report it states,“ I took my dog down to the beach for a walk around noon”(Preliminary Report). If Dez was not near the beach house during the time of the murder then it raises the suspicion of why his towel was located at the crime scene. In addition to Dez’s towel being at the crime scene there was also the smell of cologne on the towel. In Forensic Lab 4, after testing out each of our suspects (Dez, Beverly, Chloe, and Ray) cologne we concluded that the cologne does match Dez. Due to the Forensic Report it stated, “The smell that

    From a trial strategy point of view, you always start with the piece(s) of evidence you believe are most damaging to the client's case and work backwards looking for an exploitable flaw in the search and seizure procedure that would make that or those item(s) inadmissible. The further back in the series of events you can argue a fatal flaw, the more likely that the evidence and any additional materials which flowed from that particular item of evidence will be excluded. This is the practical analysis of all the times we see or hear of law enforcement arguing that there was some technical item which drew their attention and suspicion and justifies their hunch that criminal activity is afoot.

  • Ballistics In Crime Scene Investigation

    1627 Words  | 4 Pages

    If there was no weapon found at the scene and there are other evidence clues that lead to a suspect, and if the suspect had a firearm the forensics team would get a warrant to retrieve the weapon so it could be tested. When the weapon is being tested, it will allow the the bullet have individual marks that will be compared to the ones found at the scene. All of these comparisons are done under a microscope since technology has improved and it is easier to make matches. According to Young & Ortmeier (2011) “class characteristics include weight of the projectile, direction of twist of the riffling, degree of twist of riffling, number of lands and groves, and width of lands and groves.” Even though guns from the same manufacture will never have the same riffling, lands or grove. When evaluating two cartridge casings the examiner will be looking for manufacture, the size of the firing pin as well as the location. The FBI has made a integrated ballistic identification system (IBIS) it's a database that helps crime labs with comparisons where it proves one gun being used in many crimes. In addition, gunshot residue is helpful solving crimes because gunshot residue can be chemically tested. If an individual has gunshot residue it doesn't prove he or she shot the victims, it just means that they were along the premises while the gun was fired. Another

  • Familial DNA Searching

    1418 Words  | 3 Pages

    Nowadays, DNA is a crucial component of a crime scene investigation, used to both to identify perpetrators from crime scenes and to determine a suspect’s guilt or innocence (Butler, 2005). The method of constructing a distinctive “fingerprint” from an individual’s DNA was first described by Alec Jeffreys in 1985. He discovered regions of repetitions of nucleotides inherent in DNA strands that differed from person to person (now known as variable number of tandem repeats, or VNTRs), and developed a technique to adjust the length variation into a definitive identity marker (Butler, 2005). Since then, DNA fingerprinting has been refined to be an indispensible source of evidence, expanded into multiple methods befitting different types of DNA samples. One of the more controversial practices of DNA forensics is familial DNA searching, which takes partial, rather than exact, matches between crime scene DNA and DNA stored in a public database as possible leads for further examination and information about the suspect. Using familial DNA searching for investigative purposes is a reliable and advantageous method to convict criminals.

    George Pitt's DNA did not match any of the samples collected from the crime scene. The only DNA found belonged to Samantha O'Toole. The hairs found on Samantha were never tested, and most likely the butts and condom hadn't been either. Which probably means the lighter wasn't tested for prints.

    Document examiners can look at these and establish the similarities in the handwriting, and computer forensic specialists can extract logs and other data from most devices. As you can see, there is no perfect crime. The littlest piece of hair, paint, or anything left behind can be found. Suspects often miss these tiny pieces of evidence and while they look over it, it is still lurking at the crime scene. It is guaranteed that a Crime Scene Investigator will find this evidence no matter how small and use it to find, prosecute, and convict a criminal.

  • Forensics in the Criminal Justice System

    334 Words  | 1 Pages

    The criminal justice system has changed a lot since the good old days of the Wild West when pretty much anything was legal. Criminals were dealt with in any fashion the law enforcement saw fit. The science of catching criminals has evolved since these days. We are better at catching criminals than ever and we owe this advancement to forensic science. The development of forensic science has given us the important techniques of fingerprinting and DNA analysis. We can use these techniques to catch criminals, prove people's innocence, and keep track of inmates after they have been paroled. There are many different ways of solving crimes using forensic evidence. One of these ways is using blood spatter analysis; this is where the distribution and pattern of bloodstains is studied to find the nature of the event that caused the blood spatter. Many things go into the determination of the cause including: the effects of various types of physical forces on blood, the interaction between blood and the surfaces on which it falls, the location of the person shedding the blood, the location and actions of the assailant, and the movement of them both during the incident. Another common type of forensic evidence is trace evidence. This is commonly recovered from any number of items at a crime scene. These items can include carpet fibers, clothing fibers, or hair found in or around the crime scene. Hairs recovered from crime scenes can be used as an important source of DNA. Examination of material recovered from a victim's or suspect's clothing can allow association to be made between the victim and other people, places, or things involved in the investigation. DNA analysis is the most important part of forensic science. DNA evidence can come in many forms at the crime scene. Some of these forms include hair; bodily fluids recovered at the crime scene or on the victim's body, skin under the victim's fingernails, blood, and many others. This DNA can be the basis of someone's guilt or innocence; it has decided many cases in the twentieth century. As the times continue to change and the criminals get smarter we will always need to find new ways to catch them. Forensic science is the most advanced method yet, but is only the beginning. As the field of science grows so will the abilities of the

  • Collecting the Evidence From a Crime Scene

    1095 Words  | 3 Pages

    Blood stains are one type of evidence that can be found at a crime scene. Blood that is still in the liquid form should be picked up on a gauze pad. Once the blood is dried thoroughly it should be refrigerated and sent to the Laboratory (Andrus et al., n.d., para. 1). If the blood stain is found dried on clothing, the officer should wrap the piece of clothing in clean paper and place it in a sealed and labeled container. An object with dried blood stains needs to be sent to the Laboratory if it is small enough. If the object is too large to send, then using a clean knife the stain needs to be scraped onto a clean piece of paper, which then can be folded and placed in an envelope (Andrus et al., n.d., para. 2). When collecting autopsy blood samples, the officer should request that the pathologist obtain the sample directly from the heart and place it in a yellow or purple stoppered vacutainer. If the victim is still alive but in serious need of a blood transfusion, then the pre-transfusion blood sample needs to be obtained promptly before the hospital discards it (Andrus et al., n.d., para. 4). It is important for the Laboratory to receive all blood samples within 48 ho...

  • Ballistics

    Much like in Toms case, most investigations start with a crime having been committed. Forensic ballistics and firearm investigation start when there are bullets, cartridges, a weapon, or any combination of the above found at a crime scene. With the evidence, a crime lab can search for clues on these items that could lead to a suspect or possibly prove that the items were used in the crime. By comparing the markings on bullets or cartridges found at the scene with those fired from a suspect’s weapon, a ballistics expert can often determine if the rounds came from the same weapon. Just the act of cycling a cartridge through a weapon without firing it can leave permanent scratches in the case that are unique to the weapon.
