What was the most important piece of evidence?

The most important piece of evidence in this case was the ink powder that they found. Although this is a piece of circumstantial evidence it was crucial to finding the correct killer in the case. The ink powder was a piece of physical evidence, which usually only narrows the suspect pool down to a group but in this case it led the CSI investigators to only one person. When combining the ink powders (fiber evidence), which lead them to the student copy center, and the other physical evidence, such as the drawings, the CSI investigators were able to pinpoint Kevin Greer as the killer. Although there were other pieces of evidence that really got the case started if it had not been for this piece of evidence the CSI might have put the wrong person, the art teacher who they originally suspected, in jail. The find of the ink powder really just pulled the case together and connected all the dots for the CSI investigators.
