Abstract
Crime Scene Investigation (CSI) means taking all lawful methods,
processes and procedures that lead to solving crimes and detecting
the truth.This study aimed to evaluate the Palestinian Police
Agency (PPA) employees’ perceptions towards the experiences
in the documentation, collection, preservation, packaging and
transportation of biological traces from the scene of crime. An
item-based questionnaire was designed with this aim in mind, and
its reliability as well as validity were tested. The study’s target group
included (244) PPA-affiliated crime scene investigators and officers
who served in the governorates of Hebron, Jenin, and Ramallah
during summer of 2022. The majority of respondents expressed
agreement or neutrality regarding the technical procedures used at
the crime scene. In general, PPA employees have positive experiences
with the preservation, documentation, collection, packaging, and
transportation of biological evidence from the scene. The study’s
findings make it abundantly evident that the average for each
paragraph was greater than (3.57), demonstrating that PPA personnel
working at the crime scene generally had sufficient experience
handling forensic traces. However, preservation and collection of
biological traces especially DNA sources from the crime scene were
the lowest with a total averages of (3.40). While the searching and
documentation of the crime scene section, and the packaging and
transportation of the biological traces from the scene of the crime the
total averages were (3.69) and (3.62) respectively.
In addition, there was a significant difference (P < 0.05) between the respondents regarding to the three working places, age, and ranks. This study recommending the decision makers in Palestine to pay attention to the technical procedures at the crime scene and employ a trained team that has sufficient knowledge and skills to deal with biological forensic traces at the crime scene. This study also recommends conducting deeper analytical studies to include all departments and entities working at crime scenes in all governorates in Palestine.
