Any floorplans or details, besides some published pics of Ms. Brown's apt?

You killed her didn't you?

Gotta love this quote from that article:

>> The most salient point of comparison is more likely the $29.5 million that Bob Weinstein has been asking for his 14-room Beresford penthouse (not in the tower) since he listed it in 2009. (The listing for the apartment, which was available until just a few weeks ago, has been pulled, suggesting that it may have been snatched up in the luxury buying craze sweeping the city).

Let's see. The apt was on the market for 3 years, no price drops during the entire period, and now "no longer available" rather than "in contract". Yes, that most definitely suggests "snatched up".
