The wound on the right side of Libby’s neck had five red lines on the edge of the wound. They came out from the wound’s edge and were around 1 mm wide with space between them. These abbrasions are at the center of the discussion about what type of knife could have been used.
In his original autopsy report, Dr. Kohr indicated these marks
could mean a serrated knife was used. But, he said as he’s thought more about it in recent months preparing for the trial, he thinks the marks would be more consistent with a handle or something other than a serrated blade.
In court Wednesday, he testified he thinks a boxcutter was the weapon used. The thought came to him, he said, when he saw a boxcutter on his workbench in his garage and
the thumb grip had several parallel lines on it that he thinks could have made the marks on Libby.
That was a recent conclusion, though.
In his deposition with defense attorneys in February of this year, Kohr said the weapon could have been anything from a pocket knife to a kitchen knife. He did say in the deposition that the wounds were not classic serrations and he was already walking back his serration conclusion from the autopsy reports.
