Download file to see previous pages Due to the certification of more technicians, a lot of information on the shape of bloodstain is being used in the conclusion of crime events. Blood stain pattern analysis is the assessment of the nature, position, and distribution pattern of bloodstains that should enable an investigator to deduce the physical actions that took place at the scene. The outcomes obtained from the analysis give extra information to medical practitioners when determining the time the victim died. Certified bloodstain pattern analysts are normally used in offering explanations on blood spatter patterns and supplementary verifications at the crime scenes. This assists in the disclosure of vital exploratory information; like the positions of the casualty, the attacker, the items at the scene; the weapon that created the spatter and the number of blows, blast, or stabs the victim received. It can also be used to agree or contradict the report the wounded, suspects or observers give, hence ensuring that an innocent person is not condemned. Basically, inert bloodstains are as a result of the gravitational pull. They are normally evident on the various surfaces like the floor, wall, or the clothing. In carrying out crime Scene investigation therefore, documentation of all stains must be done. During blood stain pattern analysis, investigators always apply the physics, mathematics, and trigonometry laws, which assist the investigators to acquire information which enables them to determine the actions that took place; the individuals who were there, and the authenticity of the self defense declaration of the alleged doer. In the crime scene, there may be numerous areas with blood spatters. Identification of all locations with blood spatters and carrying out the necessary analysis is therefore vital. Moreover, after the scene has been documented, the resolution of the course and succession of actions enables the CIS in laying strategies for the collection of blood samples from the most rational sites. When careful analysis of the scene is done, accurate representative blood samples will be presented to the crime laboratory for analysis. Introduction Blood pattern analysis assists investigators in the determination of the source of the blood, the distance through which the blood traveled before landing, the form and the bearing of the force that caused the blood stain, the object used to produce the bloodstain, and the position of the casualty and the attacker during and after the bloodshed. Normally small blood spatters are as a result of a lot of force having been used. In order to obtain accurate results, blood pattern analysts must be careful in doing the assessments. Blood spatter as evidence Due to the gravitational pull, the shape of a free falling drop of blood is spherical. The force of gravity results in surface tension which makes the blood molecules to adhere on one another. Due to surface tension, the distance through which the drop of blood falls does not affect the spherical shape (Chisum & Turvey 374). The drop of blood will only break after hitting another surface or when force is exerted on it. When a blood drop hits an impermeable, smooth, and firm surface for instance floor tile, the probability of it forming a spatter in minimal. Freely dipping blood forms huge circular stains. Rough surfaces interfere with the surface tension of the blood drops, thus resulting in spatters and uneven stains having serrated edges.

Contemporary Issues in Law Enforcement: Crime Scene Investigations and Death Investigations

...when there are not enough officers to maintain several rooms while the investigation is on-going. This means that one person may have to play two roles: investigate the evidence and maintain it at the same time. So what has to be decided is how to manage manpower to cover a large area and maintain integrity. Can everyone be trusted to maintain the evidence when not in sight of another officer or investigator? Who watches those who take fingerprints and other forensic evidence to ensure that they are doing it correctly and not damaging the evidence in the process? Other parts conducted during the crime scene investigation are the...

Bloodstain Pattern Analysis

...Bloodstain Pattern Analysis Bloodstain Pattern Analysis Introduction The concept of BPA (Bloodstain Pattern Analysis) is referred to the opinion that when blood exits from an individual’s body or an object is covered with blood, it results in the production of patterns that can be analyzed and interpreted. These patterns can be witnessed in various criminal scenes and crime scene investigators predict that in the event of a violent crime, there will be existence of bloodstain pattern. The analysis of these patterns and the outcome of these analysis in conjunction with the event or the situation in which these patterns are found and the level of reliability of these patters are dependant on the individuals who have gained training... ....

However, the most common method is to ; “use the fingers or tweezers to pick up hair, place in paper bundles or coin envelopes which should then be folded and sealed in larger envelopes.

... technique is one of the most accurate techniques. This is attributed to the fact that it facilitates the preservation of the samples for additional chemical and biological analysis (Gardner & Bevel, 2008). Additionally, the hyper-spectral imaging used in substrate splatter analysis offers a clarity for visualizing the blood splatter; thus, necessitating easy and detailed analysis. From the above information, it is extremely essential to employ the use of splatter analysis in solving violent crimes. References Gardner, R. & Bevel, T. (2008).

Crime Scene Investigations Generalists vs Specialists

...Crime Scene Investigations: Generalists vs. Specialists Some of the positive aspects of specialization include; narrow focus of attention, officers developing expertise, improved efficiency, officers becoming more effective in accomplishing their mission and it becomes quite simple to measure effectiveness (Orthmann & Cho, 2012). This is not the case with the generalists, who do not focus narrowly on one thing, as they are not experts in any particular field. The working conditions for the specialists are good as they may work within the fixed business hours of (9am to 5pm) in controlled laboratory environments. In addition, specialists earn more than generalists do and they may have greater opportunities for career advancement... . For the...

Bloodstain analysis obscure any smaller spatters. According to Zannin and MacDowell, the blood spots point to CPR since a single gunshot cannot produce the spatter amounts on the shirt. They also point that as Horinek leaned towards Bonnie to give CPR, his left shoulder would have been aligned with the wound on her chest. This is accurate with the recording, plus the bullet punctured her lung meaning that she would have breathed the blood to anyone (Mann, 2010). Conclusion Experts should understand the fundamental principles of bloodstain pattern analysis. Serious misunderstanding can occur to those unfamiliar with this aspect. Further difficulties may arise in cases...
