Let's pretend the knife was the murder weapon. The link describes how there can be DNA evidence of someone basically everywhere in a house, yet only certain types can be used for investigative purposes.

This link is about the knife the defense claims was not used in any crime. There is no evidence that says it is the knife, and none was provided in the trial. The prosecution simply provided the knife. That does not count as evidence. It was simply a prop in the trial. The actual murder weapon was never delivered.
