A quick scroll down the Facebook page for Trolley park brought me to a post from 2012 to a Jeff Zeeman:

Just scroll to November 2012 to find it:

It looks like Jeff was the President of the North Columbia Heights Civic Association (now ran by Yavonne & David Boyd, who are thanked in more recent posts on the page for helping put on events).

After googling his name, one of the first results was this document titled "Sexual Exploitation Crimes Against Children," and the section written by Zeeman called "Meeting the Government's Discovery Obligations in Child Exploitation."

The second link to catch my eye was a picture of a Jeffrey Zeeman from an Obama fundraiser in 2007:

"Jeffrey Zeeman, 31, a lawyer at Covington & Burling LLP, said he heard about it from someone at his law firm."

Looking on Facebook again we can see that this is the same Jeff Zeeman from the photo:

One of his most recent pics is in the Hillary "H" logo.

Here is the archived page of his likes, you can see that the NCHCA is listed, along with his colleges:

So Jeff Zeeman the attorney and Jeff Zeeman the NCHCA President from the Trolley Park Facebook page are most likely one in the same.

His LinkedIn page confirms that he is the same guy from the Obama event (Covington & Burling):

It also lists him currently as Acting Assistant Deputy Chief for Policy and Legislation for the US Department of Justice -- Child Exploitation and Obscenity Section.

So the same guy who is mentioned by this small park in DC is heavily involved in pedophilia and child pornography cases in the government, both in prosecuting and in now in national policymaking.

Bonus: There's a property

We know his middle name is Howard as he's listed here:

and in an article about his wedding:

A Jeffrey H. Zeeman is the owner of a property very close to "Trolley Turnaround Park" and Pegasus Museum listed here as 1103-1105 #8 Park Rd NW:

A permit was issued for this property for "new rooftop deck specifically for #8 with spiral stair" in 2011.

Here is a screenshot of the relevant info:

And here is an image of the 2 minute walking distance to Pegasus Museum, just past the park:

What do we think guys? Is there something here? I just wanted to get more eyes on this guy and see if anyone else can dig up anything!
