DNA on knife led to arrest of quadruple murder suspect

A SINGLE strand of DNA found on the sheath of a knife used to kill four Idaho college students led police to suspect Bryan Kohberger, who visited the victims’ home 12 times before the attack, according to an affidavit released yesterday.

The public release of the court documents shed some light on the reasons police honed in on Mr Kohburger over the Nov 13 stabbing deaths of Kaylee Goncalves, Madison Mogen, Xana Kernodle and Ethan Chapin in a house in the rural Idaho college town of Moscow.

Mr Kohberger, 28, was arrested at his parents’ home nearly 2,000 miles from the scene of the murder in eastern Pennsylvania last week and agreed to be extradited to Idaho. The PHD student is charged with four counts of first-degree murder and felony burglary.

A judge yesterday denied him bail. The affidavit describes how officers discovered a bloody scene over two floors and a leather knife sheath in one room where two victims were discovered in a single bed. They matched this with DNA taken from rubbish outside of Mr Kohberger’s Pennsylvania home.
