What we know is that Sylvia Cachay, a fashion designer, checked into the hotel with a friend, 26-year-old Nick Brooks, at about 12:30 a.m. At 1:30 a.m. Mr. Brooks reportedly left the room to get a drink. When he returned at 3:30 a.m. he found cops there, with Ms. Cachay fully clothed in the bathtub, dead, and with some marks on her neck. The water had been running in the tub, and had leaked to the room below.
So, what actually happened?
Cops don't know for sure. And the case has captivated many New Yorkers. We're following developments, tonight at 11.
We're also keeping tabs tonight on the condition of Richard Holbrooke, the Special Rep to Afghanistan and Pakistan who is being treated and tested for a blood clot at George Washington University Hospital in the nation's capital.
Holbrooke, a native New Yorker, and stepfather to the children of the late ABC News anchor Peter Jennings, was meeting with Secretary of State Hillary Clinton when sources say he gasped - clearly in some kind of medical distress. We're told he walked out of her office on his own, visited the medical office at the State Dept., and was then transported to the hospital.
We'll have the latest on his condition, tonight at 11.
Turns out this is not such a good day, medically, for high-level peeps in the Obama Administration.
Earlier today, Treasury Secretary Tim Geithner went under the knife to have a kidney stone removed, at the same hospital where Holbrooke is being treated. Geithner, who was scheduled to appear on several Sunday morning TV news shows, cancelled those appearances. He's expected back at work on Monday.
One other high-profile person in medical trouble tonight. Tennis great Martina Navratilova is being treated in a hospital in Kenya, after getting sick trying to climb Mt. Kilimanjaro in Tanzania.
The 54-year-old Navratilova was attempting to hike Africa's highest peak as part of a sports charity when her lungs started filling with fluid - a condition called high-altitude pulmonary edema. Shows just how tough mountain climbing is, because Navratilova is in amazing shape. She says she was "petrified" to climb because if she failed, "the whole world" would know about it.
And now it does.
Also at 11, we're taking a closer look at the so-called "soldiers" for WikiLeaks, who this week have downloaded more than 43,000 cyber attacks on various U.S. companies, including Master Card, Visa and PayPal - all in support of WikiLeaks. Who are these peeps? And just how much damage can they do?
And exactly what's up with Mayor Mike Bloomberg? Is he planning a run for President in 2012? The Mayor earlier this week gave a speech that was clearly far beyond the scope of his job - focusing on how to create employment, and on what's wrong with government these days. Now comes word that on Monday Bloomberg is one of the headliners at the national launch of the "No Labels" party. Founders say they have organized efforts in all 50 states, with 1100 peeps coming to Columbia University for this national conference.
Sort of the independents' answer to the Tea Party. Stay tuned.
Also at 11, it's the biggest retailer in the world, but a local guy tried to fight back against and do battle with WalMart over an $80 price difference on a flat-screen TV. He got caught up in the Black Friday hoopla and showed up at 5 a.m. at a WalMart in New Jersey - only to discover that the TV he wanted wasn't available anymore. He should have showed up at midnight, despite WalMart's advertising to the contrary. So the man called Nina Pineda and got 7 On Your Side, to take up the battle against WalMart.
We'll also have any breaking news of the night, plus Lee Goldberg's weekend AccuWeather forecast, and Scott Clark with the night's sports. I hope you can join Liz Cho and me, tonight at 11, right after 20/20. And a program note: I've got a story on 20/20 tonight, about a young man from Long Island, born with severe disabilities. His name is Rohan Murphy, and he's legless. But that hasn't stopped him from becoming a supreme athlete - a wrestler. And now he's taking his life's triumphs on the road, as a motivational speaker.
