I believe based on this last warrant it is confirmed that there were only 2 trips to HT. One at 6:20 and 6:40..or something close to those times. The 4:20am time frame was originally mentioned but based on information released to the public, that trip has yet to be confirmed. The detective on the warrant mentions only 2 trips and there is video of both trips on BC's attorneys website. Neither are at 4:20am.
Oh ok! Thank you for the informative response!
