Murder In Moscow: The Experts Behind The case Against Bryan Kohberger (Part 3) (8/21/26)

Tara Martinez was a forensic scientist with Idaho State Police Forensic Services who became involved in the Bryan Kohberger investigation primarily through the collection and examination of physical evidence. After Kohberger was arrested and returned to Idaho in January 2023, Martinez participated in obtaining reference samples directly from him, including a buccal swab from inside his cheek, hair samples and fingerprints. Those materials gave investigators known samples that could be compared against evidence recovered during the homicide investigation. Prosecutors later identified Martinez as a potential expert witness and said she could explain how buccal DNA samples were collected, why known reference samples were important, and how latent fingerprints were developed and evaluated in a forensic investigation.

Martinez’s role also extended beyond Kohberger himself. In March 2024, she collected fingerprint exemplars from surviving roommate Dylan Mortensen at the Idaho State Police forensic laboratory, creating known prints that could be compared with unidentified impressions recovered during the investigation. That work was part of the broader effort to sort through fingerprints and other trace evidence associated with the King Road crime scene and distinguish potentially significant evidence from prints belonging to people legitimately connected to the house. Martinez therefore was not one of the detectives building the narrative case against Kohberger; she was part of the forensic infrastructure behind it, responsible for collecting and analyzing comparison evidence that prosecutors could use to determine whose biological material or fingerprints appeared on items connected to the investigation.
