Their main job is to look into incidents deeply, figure out what really happened, and find proof that helps in court.

Duties and responsibilities

Legal investigators have many jobs, mainly focusing on finding and keeping evidence for trials. They talk to witnesses, take down what they say, and keep this info for future use.
