In the Richard Ramirez case, several key forensic concepts were crucial to the investigation. Firstly, the use of DNA evidence played a significant role. In 2009, Ramirez's DNA was matched to an unsolved murder of a 9-year-old girl, implicating him in the crime.

Additionally, the collection and analysis of fingerprints were instrumental in connecting Ramirez to the various crime scenes. His fingerprints were found in a car and on various weapons used in the killings.

Moreover, witness testimony and the use of automated fingerprinting technology by an areawide police task force were pivotal in the investigation. These various forensic techniques, including DNA analysis, fingerprinting, and witness testimony, played a crucial role in apprehending Ramirez and bringing him to justice.
