This forensic evidence did not include specific DNA testing that could have proved Coleman's innocence. The investigation ignored the fact that the alleged murder weapon was Coleman's three-inch pocketknife, which was not consistent with the autopsy report "s stated cause of death being a four-inch deep gash in Wanda's neck. It appeared Davidson immediately assumed Coleman to be guilty based on the fact Coleman had a prior record, as a result no other suspects were investigated and no other leads were followed. .
Judge Nick Persin though less significant than the others also played a role in the outcome of Coleman's case. The judge knew the trial was tilted dramatically in favor of the prosecution. As a judge, he should have leveled the playing field between the prosecution and the defense. Beginning with the opening statements he had to be aware of the mismatch; with an apologetic opening statement by the defense that barely mention the topic of Coleman's innocence. Knowing the court appointed defense attorney's were inexperienced, Judge Persin should have explained the process and expectations to them regarding preparation for venue change, evidence review, witnesses and cross-examination. In regards to the venue change, it seems to me that the judge failed to remain impartial and should have made a decision not just based on the preparation and presentation of the arguments by the prosecution and the lack there of by the defense. It is difficult to believe that any judge would have felt a fair trial in Buchanan County was possible in such a case. The judge could have granted the change in venue based on his own knowledge of the case at this point, especially after Coleman wrote a letter requesting a change in venue that offered a better argument than his lawyers had prepared. From the opening statements and throughout the hearing it is likely that the judge could have granted a mistrial based on the incompetence of the defense attorneys.
