Personally, I think that despite the judge's order, both sides are doing their best to leak and counter-leak.
I'm guessing after Team Kobe leaked the suicidal reports and the media got its fill of "nuts and sluts" gossip on the victim, the prosecution leaked the bellman's testimony in order to get public perception back in balance.
Nobody's going to admit to this, of course, but after eight years of Clinton talking points, I have a much keener ear for the timing of when a story comes out naturally and when somebody decided it was time to come out. A lot of what has come out of the media, both pro-Kobe and pro-accuser, has that smell of controlled information. The proof to me is the dueling 9-1-1 calls - first the accuser, then Bryant. Tit for tat.
He would have given his statement to police most likely on July 1. The police have a record of his account, as does the DA, the defense, court filings, etc. There are sources galore other than his own mouth to a reporter's ear.
Also the girl, in telling her story to friends early on, (remember, the gag order was just issued), probably told them the story.
But I will say, that Luke Bray's account did say that she drove home alone. So he either didn't know the facts or the bellhop story is a load of bunk. However, it appears various media are doing independent verification, unlike the Bray account. Also, the way it was recounted in the article about Bray, it could be the reporter assuming because it is not a quote from him.
