Kohberger, 31, filed the petition for post-conviction relief Monday in Idaho's Fourth Judicial District Court, according to records obtained by multiple news outlets. The Hair Evidence at the Center of the ClaimKohberger's petition centers on what he described as clumps of unidentified hair found in Chapin's hand, hair he says his legal team never disclosed to him before he entered his plea. According to court filings, the hair was recovered from where Chapin's hand was photographed in Kernodle's bed, affixed to the bed frame by dried blood. A DNA expert hired by Kohberger's own defense team had tested hair recovered from Chapin's hand and found it morphologically consistent with Chapin's own reference hair, according to court records. It remains unclear when the court will rule on the petition or whether a hearing will be scheduled.
