The Pennsylvania law enforcement recovered trash from the Kohberger family residence, which was then sent to the Idaho State Lab for DNA testing. This evidence played a crucial role in identifying Bryan Kohberger as the suspect in the Idaho killings, as stated in court documents released on January 5th. The following day, it was reported that a DNA profile from the trash matched a tan leather knife sheath discovered on the bed of one of the victims, according to the same documents.
