 Huck then appointed major Mark Winn, as the command investigating officer, to conduct an additional investigation as per the Manual of the Judge Advocate General, otherwise known as a "JAGMAN".As per the manual, Winn's findings would include recommendations whether Pantano's case should be referred to a court martial based on the NCIS investigation and any additional factual evidence encountered during this inquiry.Winn recommended that the murder charges be dropped, because he did not find the prosecution's key witness credible.
