There are still 66 more missing pictures.

100% we know from the police report that Yaron was wearing overall jeans.  So he is in the left middle.

Police Report

The Police report said Sivan had ripped jeans and a gray and black shirt. We can see that Ellner has an all dark shirt form the mug shot.

So we can place Ellner on the far right and Sivan next to him. That means Paul or Marmari was on the far left. Paul did have a pink shirt and jeans which would match the photo.

Witnesses had seen him the dark haired man taking pictures of the other three each of whom had been on the roof on the van and had taken pictures flicking a lighter. The New York Times was also shown a picture of Sivan flicking a lighter. However it may be his brother doing the same thing later at the UMS location.

There are still 66 more pictures. You can see that they were kneeling and smoking cigarettes. This is fitting with the crime scene evidence of a number of cigarette butts as well multiple witnesses placing them there as early as 8am. They were waiting. The WTC is South East of where they are standing. You can tell by the shadow combined with all the photos showing the North Tower smoke blowing SE that this was early morning and most likely before the Tower was hit. Now these photos are from two different locations. One in the Roof of Urban Moving Systems. One is on top of the van parked at Doric towers.

Notice the chain fence in the background and that they are sitting on top of a van. Sivan and Yaron, mostly likely Ellner took the picture as he is seen with Yaron later with the same background.

Same fence from when I visited there.
