p.s. In some public tennis courts there is no schedule. People wishing to play simply hang their raquette on a hook board in the court, and wait until the half hour mark. Then players must leave the court to make way for anyone waiting. EB could have been tricked, maybe via a phone call. Are there any known facts about the scheduling method?
Track, here is the tennis schedule answer I received from RB:
1. There was no schedule;
2. If courts were open you played and if not, you wrote your name in on a chalk board and waited;
3. The only reason anyone would go there was to play;
4. You needed a summer membership and EB didn't have one;
5. We only played the week before because the supervisor was a personal friend of mine ;
6. There was a time limit if someone was waiting;
7. When I showed up at around 7:00 pm there weren't many people there;
Some other info:
1. The only person she would have played with was me (ironically, the police argued we'd broken up)
2. Liz never took her racket, had no tennis balls and wasn't dressed for tennis and these things weren't in her car;
3. The supervisor was there that night, knew Liz well, and said he never saw her or me;
4. Her car wasn't parked near the tennis courts;
