Working as fact finders, criminal defense investigators serve a critical role in the justice system, both in private and public / indigent defense cases. Investigators do not provide legal advice. Examples of what a criminal defense investigator does include:
Conduct surveillance, mobile and stationary
Locate and interview witnesses, including the alleged victim
Canvas an area to locate additional witnesses and camera footage
Develop additional leads for the attorney to follow up on
Serve subpoenas on witnesses for upcoming trial
