DNA of Idaho Student Murders Suspect Matched Sample From Knife Used in Killings

The DNA of Bryan Kohberger was a statistical match to the sample collected from the knife used in the Idaho student murders. A DNA sample from the Kohberger family’s trash also helped investigators focus on Kohberger as the suspect.

The DNA of Bryan Kohberger, 28, was a “statistical match” to the sample collected from the sheath of the knife found at the scene of the Idaho student murders. The Federal Bureau of Investigation (FBI) initially built family trees from the sample collected to determine the contributor of the unknown DNA.

However, according to Burnside, the process did not provide substantive evidence which impelled the FBI to use an STR analysis. This means that a comparison was made between the sample collected and the DNA taken from the Idaho student murders suspect.

According to Ruiz, apart from the DNA collected from the knife, a sample was also recovered from the trash found in the Kohbergers’ residence in Pennsylvania. Thereafter, the sample sent by the law enforcement to the Idaho State Lab was also used to help investigators focus on Kohberger as the suspect of the Idaho student murders.
