The Jack the Ripper case is one of the most infamous unsolved serial killer cases in history. However, in 2014, a team of researchers claimed to have identified the killer using forensic analysis of a Victorian-era turkey baster. The researchers used a technique called comparative genomic hybridization to analyze DNA from the baster, which matched DNA from a living relative of Aaron Kosminski, a man named as a suspect at the time. While the case is still disputed, it showcases the potential of forensic science in solving cold cases. When using comparative genomic hybridization: *

Use DNA analysis to identify potential matches.
Build a family tree to connect the DNA match to the suspect.
Verify the match through additional testing and investigation.

5. The Lindbergh Baby Kidnapping

The Lindbergh baby kidnapping was a highly publicized case in 1932, where the 20-month-old son of Charles Lindbergh was kidnapped and murdered. The case was solved in 1934 when a German immigrant named Bruno Hauptmann was arrested and convicted of the crime. Forensic evidence played a crucial role in the case, including a ladder found at the scene that was matched to a ladder owned by Hauptmann. Additionally, a gas station attendant identified Hauptmann as a man who had tried to sell him a carbonated beverage that contained a note demanding ransom. When analyzing forensic evidence from a crime scene: *

Document and collect all evidence, no matter how seemingly insignificant.
Use forensic analysis to identify potential connections to the suspect.
Verify the connection through additional testing and investigation.
