Regarding the Ramsey case - The DNA evidence of course needs to be pursued and fortunately in the day and age, if there is any DNA extract remaining, genealogy can possibly identify whose DNA it is. However, the location and trace amount of the DNA source leads me to believe it may be spurious - possibly contamination. For example, this was during an era when pathologists would be doing an autopsy on one body, then come over without changing gloves and looking at a homicide victim. I've told Colorado analysts to identify all bodies in the morgue at the time her body was there. During this time clothing evidence would be hung up in drying cabinets with items from other cases in some agencies causing cross transfer. Until they exhaust all sources of contamination, I am skeptical about the probative nature of this DNA. I want to see DNA coming from sources I know the offender touched such as the garotte. IMO, the other evidence in this case such as the garotte that was just placed around her neck and made from materials in the house, the ransom letter written on a notepad from within the house etc. indicates this is a staged crime scene and a very limited suspect pool. I can not comment any further than that at this time.
