Slain Idaho student Kaylee Goncalves’ dog was found unharmed in her room after she and three others were murdered. But now the Goldendoodle may be the key to solving the murder. Newly released court documents show that a search of Bryan Kohberger's apartment found 13 strands of hair, including one from a possible animal or dog. The document says "it is likely that (Kohberger) had blood or other trace evidence on his person, including hair from Goncalves dog."
