Interviewing potential suspects:
In order to find out who the actual culprit is, the investigator will need to interview various individuals associated with the crime. He will also need to verify the location of the prime suspects at the time the crime was committed.
Investigations also include checking out if any witnesses can provide information that will help reveal the identity of the culprit.
The investigator will need to examine database and records to carry out background checks of people associated with the case.
Regular updates will need to be provided to the police department regarding the progress of the case.
Records of the investigations will need to be maintained so that they can be produced as and when required.
Testifying in the court:
The investigator may be required to testify for the case in the court of law.
Let us see how private investigators help law enforcement authorities:
An investigator collects sufficient evidence using ethical means. This is used by the authorities to press charges and make the arrest. This evidence may need to be presented in the court of law as well.
Many a time the police authorities have too many cases to handle. In such cases, they hand over the responsibility of investigating certain cases to private investigators. They collect evidence, interrogate witnesses, etc. so that the authorities have time to pursue more important cases.
Since a private investigator works with an approach that is different from that of the authorities, the case can be viewed from a different perspective. Moreover, they may be more experienced in certain types of cases than the authorities.
Interviewing witnesses and locating people:
Many people are not comfortable in talking to authorities. In such cases, the services of a private investigator are very useful. This is because they can locate and interview witnesses. They can easily serve warrants, subpoenas, etc.
