Excellent post! So can you charge someone with murder based on this?
Without a body, what would guarantee a link between a potential perp, and murder? Meaning, what would be the evidence that would prove in court someone murdered this young man, without a body?
An artifact used as a weapon with blood/dna and/or fingerprints on it from the victim, and dna from the accused?
Photographic evidence of the crime?
It's a tough case without a body. If assumed Gannon is dead, without a body, LE relies on circumstantial evidence. That is what I believe the trips to the house, and to the search sites, are all about.
Any charge other than murder/manslaughter/involuntary manslaughter, IMO, is NOT what LE is seeking. I think this young man is deceased, and without a body, the just mentioned charges become more difficult to prove in a court of law.
Very interested in others opinions regarding the matter.
