Playing devil's advocate here. If she went there for a purpose, why did she take her walkman (if that is her walkman they found)? Her outfit of sweatpants, T-shirt, sneakers, jogging bra, and walkman could be a red herring. In other words, if someone lured her there (which I believe happened), the one who lured convinced her to dress as a jogger so her demise could be dismissed as a random act of violence.
How convenient for the police to have a fall guy already in custody. Now they don't have to dirty their hands by confronting Condidit.
That Anne Marie Smith gal said that condidit was big on disguises.
Perhaps Chandra Levy wasn't running at all, and only wanted to appear as a runner. How much would Chandra stand out if she dressed like a runner and was on a running trail where runners are a dime a dozen?
Perhaps a change of clothes was in the backpack for her flight home, and the sweat pants and sports bra were 'throwaways'.
More telling is that her walkman wasn't taken, suggesting a targeted murder, a serial attacker doing so for thrills, or her stumbling onto a situation(such as a drug deal) that gave someone a reason to risk killing her(perhaps even unintentional, as in a hasty reaction).
Question to all: Why were her remains found over a large area? Results of animals, erosion, or purposeful dismembering?
