Guess I'll have to jump in again, although it's not my preference. On page 8 of this thread I posted the detailed preliminary report from the NTSB. I also posted the whole audio from the tower.
For those of you that are prone to conjecture rather than reading I think you should take the time and read. There are a lot of things that are not being mentioned anywhere but on that report, which goes into a second by second the history of the accident.
The interesting part of the "History of Flight" part of this accident starts at Page 5:
5 of 20 DCA25MA108
This information is preliminary and subject to change.
"
At 2046:02, a radio transmission from the tower was audible on flight 5342’s CVR informing
PAT25 that traffic just south of the Wilson Bridge was a CRJ (flight 5342) at 1,200 ft circling to
runway 33.
CVR data from the helicopter indicated that the portion of the transmission stating the CRJ
was “circling” may not have been received by the crew of PAT25. The word “circling” is heard
in ATC communications as well as the airplane’s CVR, but not on the helicopter’s CVR.
At 2046:08, the PAT25 crew reported that they had the traffic in sight and requested to
maintain visual separation. The controller approved the request. At this time, the distance
between the two aircraft was about 6.5 nm. Figure 2 shows each aircraft’s approximate
position at 2046:02, when the controller first advised the crew of PAT25 of flight 5342.

The Google Earth image above is incredibly telling!! When the PM said "we have a visual" Flight 5342 was 6.5 Nautical Miles away. That's a long ways at night when flooded by a ton of lights everywhere you look, but definitely not impossible...
More importantly though, The white "visual line of sight" between the two aircraft is exactly right over runway 11,
at the same time that another similar aircraft had just taken off and was climbing towards the North.
Again, This is not over yet. All speculation and assignment of guilt is way too premature. Which aircraft was PAT25 looking at???
