Ok, I see your point. But what about this: if Chandra knew that park, I would say it would not be unusual for her to go jogging there. But what are the odds that this girl, who had looked up information on Gary Condit's website, then Klingle mansion, then went to the park just happened to be the only victim that ever got killed by him? If that's what happened, then she is the one with the really bad luck.
A little better if hr routine included a daily workout and her membership ended April 30, and this was May 1.
The thing that nags me the most about this is Gary's disposal of the watch case. The second thing that bugs me is it is quite possible she intended to "kill two birds" by meeting Gary and by jogging. If they met and Gary left while she went on to jog, his denial about knowing her might of cost her her life if the she was still alive after the attack.
