Investigators work with law enforcement agencies, individuals, and businesses to investigate and solve crimes to secure a successful conviction. They conduct detailed investigations of complex criminal activities and other violations of local, federal, or state law and collect, analyze, and preserve evidence. They direct crime scene investigators and other law enforcement members while at crime scenes and utilize deductive reasoning and analysis to make informed decisions and conclusions that lead to prosecution.
Investigators write detailed case reports, file and maintain records, coordinate search and arrest warrants, arresting suspects as needed. They operate firearms and electronic surveillance equipment and testify in court regarding case evidence and findings to secure a conviction. Investigators undergo continuous training and development as required and must maintain strict confidentiality. Investigators need a bachelor's degree in criminal justice or related fields and equivalent training at a federal law enforcement college.
