Forensic crime scene analysis.
Forensic crime scene investigations are conducted through asystematic process which involves
the following key steps.
1. Establishment of the scene dimensions as well as identification of potential safety hazards
in the scene through location of focal points of the scene and in this case, it is in the
living room (Saferstein 2001) .
2. The next step is establishing security of the region in order to control access by cordoning
the area with a yellow crime scene tape. According to Locard ’s Exchange Principle,
every person who enters or exits the scene will add or subtract material from the crime
scene, hence the need to cordon the area from unauthorized access (Saferstein 2001) .
3. The next step is to develop atheory relating to this offence which appears to be homicide.
Through planning and communication, the team will be able to develop an evidence-
collection strategy taking into consideration weather conditions, time of day and other
factors. After this step, primary survey will be conducted through identifying the
potential valuable evidence to be collected, take notes and capture initial photographs of
the scene and the evidence (Meloan et al. 2000) .
4. The scene will then be documented through the use of digital video cameras and 3D
scanners with an aim of collecting information which can help to provide guideline
towards solving the case. When collecting information from the crime scene, the forensic
investigation agencies will seek to collect information that is in the form of photographs
taken from the scene, trace materials from the entry point, low level DNA samples from
areas of contact such as from the victim body parts that possibly would have come into
contact with the offender. In addition, other items that might contain biological evidence
as well as latent finger prints such as from the furniture and the body parts of the victim
will be screened for potential information to be collected (Saferstein 2001) .
Forensic lab analysis.
First of all, the data collected will be captured and stored in respective locations while only
authorized examiners allowed to access the evidence. The common forensic analysis techniques
that will be adopted in analyzing the evidence presented include DNA analysis, blood splatter
analysis, witness statement analysis and the physical evidence collected evaluation to determine
whether the death of the middle aged victim was caused by aprevailing health condition such as
cardiac arrest or it was caused by an offender who gained access into the house and killed the
victim (Saferstein 2000 ).
Through DNA analysis, samples of contact with the unknown assailant will be analyzed so as to
determine on whether the victim was killed or she died anatural death. The Bloodstain pattern
analysis/ blood splatter (BPA) is another technique that will be used whereby it is the
interpretation of bloodstains at a crime scene in order to recreate the actions that caused the
bloodshed if it is anatural death or the victim was killed (Meloan et al. 2000) .These analyses
coupled with witness account statements as well as the physical analysis will provide an
opportunity through which the case can be solved by the forensic analysts providing guideline
whereby they will scientifically determine on whether the victim was killed or she killed herself
(Saferstein 2001).
