I did a bit of a search for a link for the bin lorry being first in. This point was discussed on QA thread 1 and QA thread 2. Also discussed on thread 2 QA was that no other vehicles were parked there, before the bin lorry entered. I am speculating that as posters were in agreement in the discussions I read through, on both issues, this info therefore came from QA, with the family, or a TV interview with Nicola and the interview no longer available, like many of the interviews. I think QA as no MSM link found.
