Heard something similar on the stream just a few minutes ago. Something like: we are trying to correlate the timelines of data from Falcon to the timing of the Range Safety Officer ...(turning on?)... the flight termination system.
Edit: Falcon Launch Control on "We are trying to correlate timelines and compare data with what they were able to see with down range cameras and put together what happened. We stopped receiving data at 2 min 19 sec from the vehicle. It is still not clear exactly what happened and why... At this point we don't have additional information we can provide on NASA Television until the contingency Press Conference, no earlier than 12:30? ET."
