CRIME SCENE INVESTIGATION 6
Acriminalinvestigation is one of the fields that require professionalism incarrying out the process. Identification, collection, preservation,and analysis of the evidence should be thoroughly recorded anddocumented. The process of collectionshould always commence with the most fragile objects, for instance,the items that can easily get lost or disappear from the crime scene.In addition to that, a lot of consideration should bedevelopedtowards the things that must bemovedout of the crime scene(Fisher, 2012). Photographsand images should be taken and documented since they are essentialtools in the investigation especially if they accompanied thepremises of the accusations in the crime case.
EvidenceThat I Will Collect from the Crime Scene and Its Importance in theInvestigation Process
Forinstance,in our case, the first evidence that ought to becollectedfrom the scene of the crimewas the images and photographs of the scene. The position of the bodyof the lady was lying on plus the items that werepresentedin the narration were very crucial in analyzing the situation. Theycould give the investigator thereal impression ofwhat happened at the scene before anyone could have tampered with theplace. The proximity of the wall, the traces of the grass on the bodyof the woman and the jeans at the scene could be revealed andinformed analyzationand arriving at the set of possible occurrence that might have takenplace atthe crime scene. It is due to this fact that the investigator willrefrain himself from unnecessaryinvestigations that can lead to the loss of time, such asinvestigating a homicidein our case.
Thesecond evidence that I would have collected is the freshblood stainsat the scene of the crime, both inthe woman body and on the ground. It will allow DNA examination inthe process of arriving at the exact criminal offenders who couldhave murdered the woman. Also,the collection of other loosely biological evidence, such as the wetareas on the woman body, the grasses and any other objects thatfingerprints can be retrieved will form thefirm basisfor investigating such crimes. Biological evidence alongside thefingerprints will be ofprimary importance in theassessmentof the specific individuals and criminals that might have been at thecrime scene (Lee,& Pagliaro, 2013).The fingernails will also form part of my evidence collected from theplaceof the offense.It is the type of proofthat one can match to the particular person it came from even afterseveral months have passed after the offensewascommitted.Known samples from the victim and suspect will beneededin this scenario for clearcomparison.
Lastly,I will collect the assets and materials atthe scene of the crime,such as the t-shirt, handbag, the jeans as they can beusedin matching and investigating the potential suspects in this case.These items also may contain biological information such as urine,blood,and sweat. The belongings also will reveal the possible intentions ofthe criminal behind this act.
Meritsof Attending the Scene of Crime where the Woman Body was Found
Visitingthe crime scene where the body wasfoundwill provide an in-depth primary analysis of what exactly took placeas opposed to the secondary data. The second person narration as inour case is likely to leave out vital information that can lead tothe arrest of the real people behind such acts. For instance, onewill be able to view the body position, any landmarks on the groundsuch as footprints and any possible escape points from the scene.They form the major basement for the investigation process. As aprofessional investigator,I will be in a good position to secure the place of the crime scene,identify all the necessary evidence available atthe site ascompared to passers-by, like in our case. One can estimate the exacttime that the crime wascommittedwhen he or she attends the crime scene. The distances and the anglescan also bemeasuredwithrespect tothe sceneand the possible entry and escape points of the criminals. The facialexpressions, eye color, the faciallook of the woman can only beidentifiedif an investigator visits the scene of the crime.Here I will opt for attending the scene from clear, detailed andprecise evidence alongside the narration of what happened at thescene.
ForensicScience Evidence that I would Request from the Pathologist to Findout Whether a Sexual Assault Occurred
Forensicscience evidence is relevantin the caseat arriving on ifthe actwas a sexual assault. There are somesamples that I will need from the pathologist in determining if thewoman wassexually assaultedbefore she died. The semen and any other liquid found in the virginaltrack of the woman will be essential in examining the possibilitiesof sexual abusein this case. Also,the pathologist will have to give me the samples of any foreignblood stains found in the private parts of the woman. The images ofthe vaginal track and the surrounding areas any fingerprintsfound on the woman body especially the private parts the strains andinjuries images on the woman body the overalltemperature and the heartbeatof the woman beforeher death (Dutelle, 2016).
Besidesthe above samples, I will also need the woman inner clothing’s plusits images if they had beentampered with.Any clothing from the crime scene will be essentialin analyzingthe sexual assault.
Theother Samples that I Would Require to act as Controls in this Case
Controlsamples are necessaryin our case in matching the suspect to the available evidence in thescene. Forinstance,in this situationof a woman,the first suspect is the man walking with his dog. I will need to gethis fingerprints,personal information and even the information about his heartbeat andtemperature at that particular time to act as the control evidence. Iwill alsoneedthe samples from the adjacent unstained areas,besidesthe crime scene to note the difference in the analysis of the two.After collecting the grass samples and other plant vegetation in thescene,I will need to collect the same from nearbyplaces as the controls. The possible suspects, the residence and theidentified or mentioned individuals who might have beenseennear the crime scene must be the controls. That is, the fingerprints,DNA and fingernailsof these peoplemust be collected todetermine whether theymatch any that has beencollectedfrom the scene.
