Hillary or Susan, Hillary or Susan!!
You forgot to mention all those beauties at Smith College in western Mass.
Another theory to throw out there....Some have speculated that the perp looks ill/dying (we'll know soon). Are the Ramsey's well off enough to pay off a guy to admit to the murder? (the perp receives the money and passes it on to someone he cares???) The ex-wife's alibi statement doesn't make sense...The DNA match? Will wait to hear more on that..The Ramsey's know the details of this investigation and could pass it on to this person - hence the knowledge displayed by the perp.
The Boulder Police desperately want this case to be over and solved - hope they are investigating this better than we are....
Ok...taking tin foil off...
