What is Serology and why is it important in a crime scene?

Forensic serology focuses on the characterization and identification of biological (body) fluids found at crime scenes. These fluids can include blood, saliva, semen, and other bodily fluids. Serologist play a vital role by collecting samples from the crime scene, which involves documenting the physical evidence and screening it for the presence of biological material. Often this analysis begins with visual examinations, but often may involve advanced techniques such as chemical tests or microscopic examinations.

Serology in the Ramsey case: 

Blood Samples: During the investigation, blood samples were collected from various location within the Ramsey house. DNA was recovered from JonBenét’s body and clothing indicated the presence of an unidentified male’s genetic material. This DNA was mixed with JonBenét’s blood and possibly that of at least two other individuals.

Underwear Analysis: A significant piece of evidence was a drop of blood found in JonBenét’s underwear. This sample was complex because it contained the mixture of DNA from multiple sources, JonBenét herself as well as at least two unidentified individuals. Due to the complexity of this mixture sample, continued scrutiny and debate around the validity of this DNA continues today.

What are CORA Files and how are they related to the Ramsey case?

The Colorado Open Records Act (CORA) mandates the public’s access to most public records for inspection upon request. The following files were obtained from the Boulder District Attorney’s office in response to a CORA request regarding the DNA testing in the Ramsey case.

DNA evidence has played a crucial role in both exonerating certain individuals and potentially identifying the perpetrator.

Initial Discovery of DNA Evidence: Following JonBenét’s murder on December 25, 1996, various samples were collected from the crime scene, including under her fingernails and from her clothing. These samples were subjected to DNA testing.

Exoneration of Family Members: In 2008, it was confirmed that DNA found on JonBenét’s pajama pants did not match her parents, John and Patsy Ramsey, or any close family members. This finding was significant as it formally cleared them as suspects after years of speculation and scrutiny.

Unknown Male DNA: The DNA evidence collected indicated the presence of an unknown male contributor. This information suggested that an intruder may have been involved in the crime rather than a family member or someone close to them. (Please see the UM1 DNA Profile)

Advancements in DNA Technology: Over the years, advancements in forensic science have led to improved methods for analyzing DNA samples. Law enforcement officials have expressed hope that new technologies could provide further insights into the case by re-examining existing evidence.

Cold Case Review Team: Recently, a Colorado Cold Case Review Team has been established to reassess the investigation using modern forensic techniques. They are working with leading experts to analyze remaining DNA samples with cutting-edge technology that may not have been available during earlier investigations.

Public Genealogy Databases: There is interest in utilizing public genealogy databases to identify potential suspects through familial connections based on DNA analysis. This method has been successfully employed in other cold cases and could be applied to JonBenét’s case if sufficient evidence is made available.

Ongoing Investigation: The investigation into JonBenét Ramsey’s murder remains open and active, with authorities continuing to pursue leads and explore technological advancements that might help solve this tragic case.

While significant strides have been made regarding the understanding and analysis of DNA evidence in JonBenét Ramsey’s case, challenges remain due to previous mishandling of evidence, the complexity of forensic science and ongoing investigative efforts.
