He drove cross-country in a white Hyundai Elantra and arrived at his parents’ house in Pennsylvania around Christmas, according to a law enforcement source. Authorities were tracking him as he drove and were also surveilling his parents’ house, the source said.
An FBI surveillance team tracked him for four days before his arrest while law enforcement worked with prosecutors to develop enough probable cause to obtain a warrant, the two law enforcement sources said.
Genetic genealogy techniques were used to connect Kohberger to unidentified DNA evidence, another source with knowledge of the case tells CNN. The DNA was run through a public database to find potential family member matches, and subsequent investigative work by law enforcement led to him as the suspect, the source said.
Kohberger was arraigned Friday morning in Pennsylvania and is being held without bail, records show.
Kohberger intends to waive his extradition hearing to expedite his transport to Idaho, Monroe County Chief Public Defender Jason LaBar said in a statement to CNN on Saturday.
“Mr. Kohberger is eager to be exonerated of these charges and looks forward to resolving these matters as promptly as possible,” LaBar said.
Even with a suspect charged, law enforcement’s work is far from over, prosecutors said.
