What does Criminal Investigator do?

On a day-to-day basis, a Criminal Investigator typically performs a range of tasks that can vary depending on their specific role and the stage of the investigation. Here are some common activities:

  1. Gathering Information: Investigators often start their day by reviewing case files, reports, and evidence collected in previous investigations. They also gather new information from various sources such as witnesses, informants, or surveillance operations.

  2. Interviewing and Interrogating: Investigators conduct interviews with witnesses, victims, and suspects to gather additional information and to assess their credibility. They may also conduct interrogations of suspects, aiming to gather evidence or elicit a confession.

  3. Collecting Evidence: Investigators visit crime scenes to collect and analyze different types of evidence such as fingerprints, DNA, weapons, or surveillance footage. They carefully document and collect evidence, ensuring proper chain of custody to maintain its integrity.

  4. Conducting Surveillance: Investigators often engage in surveillance activities to monitor suspects, gather evidence, identify patterns, or determine their associations. This can involve physical surveillance or the use of technological tools such as video or audio recording devices.

  5. Analyzing Data and Evidence: Investigators review and analyze collected information and evidence to identify patterns, connections, and potential leads. They may use specialized software or database systems to process data effectively.

  6. Collaborating with Other Agencies: Criminal investigators often collaborate with other law enforcement agencies, forensic experts, and legal professionals. They share information, coordinate efforts, and seek specialized expertise when needed.

  7. Preparing Reports and Documentation: Investigators maintain detailed records of their activities, observations, and findings. They prepare reports, affidavits, and other documentation necessary for court proceedings or further investigations.

  8. Testifying in Court: Investigators may be called upon to testify as expert witnesses, presenting their findings, interpretations, and conclusions in legal proceedings.
