Introduction

Criminal investigation is defined as a process that involves an examination of what has happened and identifying those responsible, and developing admissible evidence.

Overview of criminal investigation

A proper procedure is followed that includes a number of steps such as initial information and scene assessment, identification of evidence, its analysis and interviews, the construction of events and preparation of the case for prosecution.

Crimes investigation techniques

There are several investigation techniques that are utilised investigating a criminal activity and these include scene security to restrict any kind of access to prevent contamination, systematic searching by utilising zone search, photography to record the scene, measurements to establish the location and relationship of evidence and scene reconstruction by utilising physical evidence.

Evidence identification and collection

This includes analysis of fingerprint, blood, DNA, weapon, cCTV footage and electronic record, and they are then collected by utilising appropriate methods.

Evidence documentation and preservation

The collected data needs to be handled and transferred appropriately for proper examination. It needs proper documentation and preservation to prevent any kind of contamination, deterioration etc.

Interviewing and questioning techniques

Interviews all used to collect data from the victims by utilising open ended type questions initially followed by focused questions to clarify any kind of inconsistencies.

Observation and surveillance techniques

Observation is quite effective in understanding a person’s movement, behaviour, association and activities. Surveillance is carried out using CCTV monitoring and other technological devices.

Role of Technology in criminal investigation

Technology plays a crucial role in criminal investigation by way of DNA profiling, fingerprint databases, CCTV and video analysis, digital forensics and databases and analytical software.

Real life case study

On such case study is the Golden state killer investigation whereby the investigator makes use of investigative genetic genealogy in order to generate leads from DNA evidence left by the offender. This approach indicates the application of traditional DNA evidence with emerging analytical techniques to identify the offenders.
