What Is Going on With the Case?

There have been many reports that state that regarding the handwriting analysis that Merriman could not be ruled out as a possible author of the ransom letter. Well, I think they had him give over seven handwriting samples. He was questioned multiple times. He also provided police with his fingerprints. He gave blood and he gave hair as well. I can't find any documentation to state that any of this evidence would be a match to evidence collected at the scene.
