Work Towards Becoming a Criminal Investigator

Criminal investigators are individuals who investigate crimes and other events for legal and official purposes.

They’re professionally licensed, but they don’t work for a government agency like police officers do.

Instead, they work for hire on behalf of private clients.

They might end up using the results of their investigation in a criminal proceeding.

What Does a Criminal Investigator Do?

An investigator for criminal offenses helps their client prove or disprove facts relating to a criminal allegation.

They pursue leads and try to gather information that’s helpful to their client.

That helps their client pursue their claim in court.

They track down witnesses, make observations, gather records, and otherwise help their clients build criminal defenses or criminal claims.

Working on Behalf of Individuals Facing Criminal Charges

In some cases, criminal investigators work on behalf of individuals who are facing criminal charges.

In that case, they might try to identify witnesses and gather witness statements.

They might return to the scene of the alleged crime in order to conduct their investigation.

They might examine aspects of the case such as cell phone records or GPS data in order to examine and disprove part of the state’s case.

An investigator might testify in court on behalf of their client.

Working on Behalf of Crime Victims

A criminal investigator might also work on behalf of a client who believes another person or company has committed a crime.

In that case, they might want to gather the evidence in order to ask a law enforcement agency to bring criminal charges.

This might include investigating allegations of fraud, falsifying evidence, embezzlement, or all sorts of other crimes.

Steps to Becoming a Criminal Investigator

  1. Meet the age requirement. It’s 18 in most states.
  2. Get the necessary education or experience
  3. Provide proof of clean criminal history
  4. Apply for an investigator license
  5. Obtain a bond and submit proof to the State

1. Each State Has its Own Requirements

Each state has its own requirements to become a criminal investigator.

These state regulations typically require minimum education, practical experience, and character and fitness.

Every state is different, but most states have minimum age, character, and experience qualifications.

2. Experience or Undergraduate degree

Most states have several ways for an investigator to meet their education or experience requirements.

They might allow former military or law enforcement officers to meet the requirement automatically.

Many states allow parole and probation officers to use their work experience to meet minimum requirements.

If a candidate doesn’t have former military or law enforcement experience, they can usually apprentice with a criminal investigator.

The apprentice period runs between two or three years.

Alternatively, some states allow a candidate to substitute a bachelor’s degree in a criminal justice field for the experience requirement.

Joining a criminal investigator association may also be of benefit.

3. Getting Your License

In most states, a license for criminal investigations is called a private investigator’s license.

It’s the state itself that processes the applications and maintains a database of licensees.

To learn how to submit your application, you can look at your state’s informational website.

The web page for your state should have a checklist for what information you need to gather and where you submit the information for processing.

You’ll need to submit an application form, a copy of your criminal history, and other documents to prove your qualifications.

It’s the state’s licensing board that processes your application and makes a decision about whether to approve it.

4. Bonding Requirement

Most states require you to get a bond in order to work in criminal investigations.

To get a bond, you pay a small amount of money to a company.

In return, the company agrees to pay a certain amount of money if you don’t abide by the terms of your state license.

The bond isn’t an insurance policy for you.

Instead, it’s for the benefit of the public.

If you don’t do your job properly, the bond ensures that the public doesn’t suffer as a result.

There are many private companies that offer bonds for individuals seeking their criminal investigation license.

5. Work Environment for Criminal Investigators

The work environment for a criminal investigator varies by the day.

They spend some of their time sitting in front of a computer preparing reports.

They spend time in an office meeting with new clients and reviewing the results of an investigation.

The courtroom is another common location for an investigator.

When called upon, they might spend long days in the courtroom.

They might also meet with police officers at their station or headquarters in order to talk about their investigation.

However, criminal investigators spend a great deal of time in the field.

They might spend hours or even days at a time in a vehicle waiting for movement.

They might spend their days driving to follow a vehicle or driving to see a scene or speak with individuals.

They also may spend a great deal of their time interviewing witnesses or otherwise interacting with people.

The days of a professional investigator are varied.

Attorneys might frequently use an investigator to help them gather evidence for their criminal clients.

Corporations can also use criminal investigators as employees.

Insurance companies may employ investigators to look into suspected fraud.
