The harrowing detail was included in a newly unsealed affidavit on Thursday, just before Bryan Kohberger, the 28-year-old doctoral student charged with the slayings, was scheduled to make his first court appearance in Moscow, Idaho. He was arrested in Pennsylvania last week, where he was visiting his family, and flown to Idaho on Wednesday. Investigators were able to match DNA recovered from a knife sheath left at the scene with DNA taken from trash at the Kohberger family residence, according to the unsealed court document. About 15 minutes later, the car was seen leaving at a "high rate of speed."
