Murder In Moscow: The Experts Behind The case Against Bryan Kohberger (Part 2) (8/21/26)
Published 12 hours ago
Description
Taylor Maichak, a forensic scientist with Idaho State Police Forensic Services, was expected to testify about DNA testing she performed on evidence gathered during the investigation, including a group of everyday items seized from the Kohberger family home in Pennsylvania. Those items included a Band-Aid, drinking straws, earplugs, lollipop sticks, nail clippers, a flosser, a Q-tip-style swab, coffee and water bottles. Maichak generated DNA profiles from several of those items and identified an unknown male profile from the Q-tip-style swab. She then compared that profile with the unidentified male DNA that had previously been recovered from the knife sheath found at the murder scene. Her analysis concluded that the Pennsylvania male was not the source of the sheath DNA, but that he could not be excluded as the biological father of the man whose DNA was on the sheath. The statistical calculation was extremely strong: at least 99.9998 percent of the male population would have been excluded as the possible father.
Maichak also would have helped explain the much broader DNA work investigators performed as they attempted to identify or eliminate other people whose biological material appeared on evidence associated with the King Road house. Her reports documented comparisons involving numerous reference samples and unidentified DNA profiles recovered from various items, showing that the male profile obtained in Pennsylvania was excluded from several other DNA mixtures and unknown-male profiles found during the investigation. That distinction was important because her testimony would not simply have told jurors that DNA existed at the scene; it would have walked them through the process investigators used to separate unrelated DNA from the specific male profile recovered from the knife sheath. In practical terms, Maichak’s evidence would have provided an early forensic bridge between the sheath DNA and Kohberger’s family before investigators later obtained a direct reference sample from Kohberger himself, while also demonstrating that investigators had tested and compared other unidentified biological material rather than automatically attributing every unknown DNA profile to him.
