DNA fingerprinting, also known as DNA profiling, is the primary technique used for comparing the DNA profiles of a known suspect and an unknown biological sample collected from the victim. This technique analyzes specific regions of DNA known as Short Tandem Repeats (STRs), which are highly variable among individuals. By comparing the STR profiles from the known and unknown samples, forensic analysts can determine whether the suspect's DNA matches the DNA found at the crime scene.
