Forensic biology is very important to many criminal investigations by being able to use scientific evidence in entomology, odontology, anthropology, DNA testing, serology, toxicology, microbiology, and pathology. These different subfields are to provide an unbiased result that can identify a suspect, a victim, eliminate a suspect, exonerate the wrongly accused, corroborate a timeline of events, establish a time and cause of death, or even identify a weapon. Forensic biology should be applied to

behind including force of entry, fingerprints, footprints, DNA and so forth. Once evidence is collected, it is sent to the laboratory where it is tested on to eliminate potential suspects in the crime scene. Forensic DNA analysis has been used in investigations since the late 1980s. According to Forensic Magazine, the first use of DNA testing within the courts happened in England. Police force had asked molecular biologist Alec Jeffreys to use DNA to verify a confession of a suspect in two-rape murders

1. What are the four types of evidence in a criminal investigation? The four types of evidence are physical evidence, documentary evidence, demonstrative evidence, and testimony. Physical evidence is defined as tangible objects such as weapons, trace evidence, blood or fibers, and fingerprints.

As well as, investigate crimes and record evidence mostly with equipment’s such as cameras

Solvability factors absolutely should be used during a criminal investigation in order to help solve a case. Now, depending on the crime and the level of the solvability factors, I believe they should be placed in an order of importance so that investigators can focus on the higher level of importance crimes. I think that heinous crimes such as murder, sexual assault, rape, and even robbery should be investigated regardless of the solvability factors because these are the most serious crimes against
