Time from billandrew's spreadsheet says:
"4:10 am Millard (on Noudga's phone) texts Hagerman: "2." Day 31: Hagerman testimony
May 10 4:12 am Millard meets Hagerman in driveway of Hagerman's parents' home, provides a toolbox with small padlock on it."
So it was two minutes, but I don't recall how anyone knew the exact time.
Well unless those are surveillance notes, which they are not, then they are notes of MH's police statements, so of course they would line up with his testimony. BTW, we know that DM tried to influence the witnesses, so I think there's a pretty good chance he succeeded in doing so. MH was said to be sobbing on the witness stand when he testified, but I don't know whether that's because he was being honest or because he felt conflicted...
