Regarding the Carole Greenwood bit

We can also confirm via a Washington Post article written in 2003 that Greenwood does have a son who would have been 17-18 years old in 2009.

The Washington Post article from May 2003 says her son is 13 years old. She left Comet in June 2009. He would be 19 years old.

Carole Greenwood of Greenwood Restaurant has raised 13-year-old Dylan by herself.

What years did this person work at Comet?

This person is claiming that Carole Greenwood reported this to the police and the police did nothing? This is odd for a few reasons.

According to the accuser, another employee witnessed the assault of Greenwood's son. Those reports were allegedly swept under the rug by the DC police. Both Greenwood, and the alleged witness were unavailable for comment.

Unavailable for comment? Did you have a way of contacting either Greenwood or the alleged witness?

In the comments, you say

Mr. James Alefantis is listed as one of GQ's most POWERFUL men in DC. It shouldn't be a surprise that people are hesitant to step out against him

That article came out at least two years after this incident. I believe it was in 2012. David Petraeus was still a general in 2009 and in that 50 most powerful list, he is listed as the director of the CIA where he only lasted one year.

One reason this is odd is that Carole Greenwood would have been more well known in than James Alefantis was in 2009, much more famous. She certainly would have known a ton of people and had access to influential people and the press (certainly food writers knew about her.) That idea that the the police would cover up an accusation coming from her to protect Alefantis seems very unlikely to me. That seems to be projecting his fame now back into the past.

And a google search for her limited to 2008-early 2009 confirms this

She was up for prestigious James Beard award for Best Chef in the MidAtlantic region in 2008.

Washingtonian Magazine had Comet Ping Pong and Bucks on its 100 best restaurants list in early 2009. Alefantis is not mentioned. She is. 100 Best Restaurants 2009: Comet Ping Pong No. 81: Comet Ping Pong Cuisine: Chef Carole Greenwood, a locavore before the term was trendy, embellishes her thin-crust, wood-fired pizzas with everything from soft-shell crabs to pepperoni.

100 Best Restaurants 2009: Buck’s Fishing & Camping No. 40: Buck's Fishing & Camping Cuisine: Chef/owner Carole Greenwood’s fine-dining paean to the holy trinity of contemporary gastronomy: local, seasonal, organic.

Alefantis's renown grew after she left Bucks and Comet and both restaurants stayed successful. She was the one with local celebrity in 2009. In fact, this article on how the restaurants were doing after she left, spents several paragraphs on her before mentioning Alefantis. To get a sense how well known she was in 2009 check out the headline.

Carole Greenwood's Empire, Minus Carole Greenwood

The other reason this seems odd is Carole Greenwood seemed to be bulldog of a woman, not afraid of letting you know how she felt or causing a ruckus. Had the police tried to shut her down, I don't see her going quietly. If she didn't want it publicized would be one thing, but if she went to the police with it, she was obviously not trying to keep it quiet. She certainly could have gotten heard in any newsroom in washington.
