Fact: Chandra was last seen in black spandex pants and a t-shirt according to her official missing persons flyer. That would have been the attendant at the gym that gave that info. (Chandra most likely showered at the gym, put on the clothes and left the evening of 4/30.)
Fact: Chandra was found with a black spandex pants, (knotted), and a t-shirt.
So, did she meet with her killer as she left the gym? That would mean whoever killed her took her keys and went into her apartment and played Chandra on the internet for some four hours, thoroughly debunking the serial killer Geregos school of thought.
Did she go home and sleep in her clothes, (very possible, they're comfortable), and then get up, putter around the apartment for several hours, then decide to go meet "her man", go for ice cream, take a walk in the same clothes she slept in? Not likely.
This sure does make the theory that she was "taken", (quote from Billy Martin on LKL this week), from her apartment much more likely. Probably in the very early morning hours when there were very few people out and about. 4:00 a.m. scream? It would explain the same clothes being worn by her and the scream and the blanket being on the floor by the door, the missing keys, the very clean apartment, the missing watch, bracelet, any trace of Condit in her life.
