Excellent post. The facts in this story - if true - would seem to completely exonerate Seligmann, and cast doubt on the woman's entire story. The first dance ended at about 12:05. Then the woman left, was talked in to returning, and briefly danced again. At a minimum, that would have taken 5 - 10 minutes, which takes us to 12:09 - 12:15. In that same time frame, or within five minutes of it, Seligmann makes two phone calls. Seligmann leaves at 12:19, leaving him 3-4 minutes - at most - to participate in a gang rape which the woman says lasted at least 20 minutes. We have, therefore, reasonable doubt. "We have reached a verdict, your honor: not guilty."
Could be that the reason she came back to the party was the promise of money for, say, oral sex. At 12:09 (maybe as early as 12:05) she and the three guys go into the bathroom, Seligmann is first, sees that things are getting way out of hand, beats feet to establish an alibi. The other two guys stay.
He calls a cab at 12:14 (alibi #1) After 5 minutes he gets tired of waiting, knows he can't hang around, and so leaves with a friend from the party, not alone, at 12:19 (alibi #2). They start walking back to the dorm, get about about a block and a half, spot the cab he called, and get in (alibi #3). He goes straight to an ATM at 12:24 (alibi #4). At 12:25 a.m., he was making a phone call to a girlfriend out of state. (alibi #5). He then goes to a fast food restaurant (the OJ alibi #6). Goes back to the dorm at 12:46 (alibi #7).
Now, was he involved? No, I don't think so. But, the point is, he could have been.
