Forensic investigation is the application of science to criminal and civil laws. Throughout an investigation, forensic scientists collect, preserve, and analyze scientific evidence. Forensic scientists can take on different roles in an investigation, for example the role of a laboratory analyst, a field investigator, or an expert witness in court. Different types of investigations are required for different cases. Briefly outlined below are three types of forensic investigations.

Fire and Arson Investigation: The purpose of fire and arson investigations is to determine whether fires are accidental or deliberate. Evidence collected during these investigations include accelerants, tampered utilities, and specific burn patterns, which may indicate a deliberate fire.

Cold Case Investigation: Cold case investigations involve solving violent crimes, such as murder and sexual assault. The investigations usually involve the use of DNA as evidence. Technological advances have allowed for the successful analysis of DNA of aged, degraded, or otherwise compromised biological samples. In addition, samples that have previously been deemed unsuitable for testing or have generated inconclusive results may now be able to yield successful analyses.

Cyber Crime Investigation: More prevalent today than ever before, cyber crimes are crimes that involve computers, cell phones, the Internet, or other digital devices. In a computer forensics investigation, data is recovered from the computer. Computer forensics investigators have the ability to detect activity on your computer and to resurface hidden or deleted emails and data. Cellular forensics investigators can recover data, text messages, photographs, GPS, and other information from a cell phone. They may also have the ability to access hidden or deleted information.
