Kaşif Kozinoğlu autopsy report reveals presence of antimony

A new autopsy report regarding the 2011 death of former MİT Asia Region Advisor Kaşif Kozinoğlu has revealed the presence of high levels of antimony in his biological remains. The findings come 15 years after Kozinoğlu died in Silivri Prison, an event originally attributed to a heart attack.

Following instructions from the Silivri Chief Public Prosecutor's Office, a grave opening (fethi kabir) was conducted on September 12, 2026. Forensic DNA analysis confirmed with 99.99 percent certainty that the remains belong to Kozinoğlu.

Toxicological analysis of 36 different samples, including hair, nails, bone, and tissue, detected significant amounts of antimony. Specifically, the report noted 7,002 nanograms per gram in the nails and 548 nanograms per gram in the hair. Notably, antimony was not detected in any of the seven soil samples taken from the grave, suggesting the substance was not absorbed from the environment but was present in the body prior to death.

While other heavy metals like lead, nickel, arsenic, and cadmium were found in both the body and the soil, the absence of antimony in the soil has raised suspicions of poisoning. The Forensic Medicine Institute's First Specialized Board will provide the final decision regarding the cause of death.
