The set of principles involved in blood spatter analysis include- (i). Biology (properties of bl00d) (ii). Physics (cohesion, capillary action & velocity) (iii). Mathematics (trignometric analysis) Thses set of principles help the investigators to answer the following questions- 1. Distance from the target to the source? 2. The angle of impact of the blood droplets & the travelling direction? 3. The kind of force used to cause the bloodshed? 4. The material used as a weapon to commit the crime? 5. Determining the sequence of multiple bloodshed events? If any? 6. Determining the relevant positions of the victim and the perpetrator? 7. Establishing the relation between the statements of the witness and the events that took place? Features of blood droplet in flight: (i). Blood won’t separate into tiny droplets until it is acted upon by an external force & the force acting should be strong enough to overshadow the surface tension of blood. (ii). When the blood separates from its source, it acquires a spherical shape almost on immediate basis. (iii). The drop will clinch into a spherical shape due to the surface

  • Specific Crime Scene Forensics: Ballistics

    461 Words  | 2 Pages

    Specific crime scene investigators, sometimes referred to as “ballistics experts” or “firearms examiners”, are forensic specialists. They are mainly responsible for collecting and analyzing, from a crime scene, the ballistic-related evidence, including both firearms and ammunition. These forensic specialists are called upon to determine everything ranging from trajectory, to probable distances and angles when examining firearms and ammunition. A “ballistics expert”, studies (depending on the evidence collected) shell casings, bullet fragments, clips, and firearms discovered on the crime scene. They determine this while in a laboratory setting, and can analyze the evidence to solve a crime.

An analyst can describe how the blood came out of the body depending on the type of injury which took place. Blood can be looked like a flow, drip, spray, spurt or a gush (http://www.forensicsciencesimplified.org/blood/principles.html). Blood describes its velocity by its stains.

  • Latent Bloodstains In Crime Scene Photos

    When an area in a suspect location has been partially cleaned, that should always raise a red flag for investigators. Something was there and has been removed that the offender did not want anyone else to see. Whether it is blood or not remains to be definitively tested, but it is still clear that something is present and raises suspicion. Void patterns indicating that an object has been moved also gives ample reason to believe something may have been there and cleaned up, especially when it is clear it has been sitting there for a long time. Identifying and collecting these latent bloodstains can easily be done with luminol in an interior environment such as this one.

The hypothesis of a bloodstain pattern being the result of arterial spurting would be supported by identifying information within the autopsy report about a severed artery. A bloodstain analyst would require to review the bloodstain pattern by conducting an autopsy report, or verbalize directly to the forensic pathologist who conducted the autopsy report. These patterns are customarily very distinctive due to the overall quantity of bloodstains observed.

    He found that Police procedures with regard to evidence referencing, police chain of custody and overall collection of evidence. He stated that the Queensland Police Force failed the most rudimentary collection protocols and this lead to confusion in the labelling of exhibits and their actual obtaining from the accused. He further pointed out that searches were conducted in a manner that exposed the primary and secondary crime scenes to contamination. A video of the Police search showed that none of the officers involved wore protective clothing, gloves or booties; that swab testing of the car showed that the officer involved in collection conducted the Sangur strip test and actually allowed his fingers to come in contact, thus providing a false positive indication for human blood, when it was noticed that he had a small cut on his finger; fingerprint collection was done before testing for human enzymes which also could have produced a false positive due to the chemical makeup of the powder used (the force used Magnapowder which has a metallic composition and this reacted with the test strips); photographs of the boot floor showed that none of the items were laid out on white protective paper. This would also have prevented cross contamination and enabled the collection of any evidence that fell from the boot.

    When Dr. Musoke tries to treat his patient he tries to insert a needle in the patient, but his patient would not stop bleeding from the places he stuck the needle. Preston writes, “At every place in the patient’s arm where he stuck the needle, the vein broke apart like cooked macaroni and spilled blood, and the blood ran from the punctures down the patient’s arm and wouldn’t coagulate” (27). This proves the thesis because it is establishing the mysterious and suspenseful mood that is used all throughout the book. While the medical system may lower the outbreak, there are some cases where the medical system intensifies the outbreak. Preston writes in the text, “In some cases, the medical system may intensify the outbreak, like a lens that focuses sunlight on a heap of tinder” (98).
