What is Criminal Investigation?

An ensemble of methods whereby crimes are studied and criminals apprehended. The criminal investigator seeks to ascertain the strategy, motives, and identities of criminals as well as the identity of victims and might also look for and interrogate witnesses.

An effective criminal investigation officer must possess certain qualities and understand the job duties needed for the position. Investigators have to be experienced in interviewing and interrogation techniques plus work well as communicators—both verbally plus in written correspondence, to accurately relay information and document findings and progress throughout an investigation. Investigators collect information from both witnesses and suspects.

What Criminal Investigation Officers Do?

Investigators will collect evidence, control evidence chain-of-custody, maintain records, submit evidence to laboratories, and after that produce evidence as well as examination/analysis reports to your courts. It is usually essential for an investigator to learn the kinds of analysis or examinations which might be conducted on various types of evidence collected at crime scenes and/or from victims and suspects.

How They Conduct Criminal Investigations?

When something against the law is detected or reported, an investigator is delivered to the criminal investigation scene as well as the investigation begins. Evidence is collected, preserved, documented, and delivered to the laboratory for analysis and/or examination.

Investigator responsibilities include upholding the rights of offenders, victims, and witnesses and following proper procedures. The United States is a network of criminal justice systems at the federal, state, and special jurisdictional levels. Criminal laws at these levels vary, although these are based on a good US Constitution.

On coming to the crime scene, the investigator will preserve the crime scene and forestall unauthorized individuals from entering the scene so they won't contaminate the scene or compromise the additional value or integrity of evidence. Photographs must be studied of the complete scene, in addition to photos of each significant item or potential part of the evidence. Sketches and/or video footage from the crime scene may also be useful. Properly collecting and documenting evidence is imperative to the achievements of the investigation.

Interviews or interrogations could be conducted and written statements may be studied through the individuals with knowledge about the crime, the victim(s), the suspect(s), or area. Reports are completed to document the investigation from beginning to end, with the goal of a successful outcome in courts.
