O'Keefe Phone Last Interactive Events — Whiffin Timeline Slide
Whiffin's slide 82: Face ID at 12:32:04, lock at 12:32:09, Health steps at 12:32:16 and pocket state at 12:33:14 a.m., admitted as Trial 2 Exhibit 39.
About
The prosecution used the slide to identify a Face ID unlock at 12:32:04 a.m. and a lock at 12:32:09 a.m.; the health-step and pocket-state entries were derived records, not direct screen interaction. Hyde said she had not reviewed or validated Whiffin's artifact and could not attest to it, while distinguishing movement-derived activity from active device use. The lock's relationship to the Lexus Techstream trigger window remained disputed, with the original and revised timing treatments placing the events differently.
A compiled timeline slide (slide 82) from Ian Whiffin's report, admitted as Exhibit 39 in Trial 2, showing the sequence of last interactive events on O'Keefe's iPhone: a Face ID unlock at 12:32:04 a.m., a lock at 12:32:09 a.m., health step data at 12:32:16 a.m., and a pocket state entry at 12:33:14 a.m. The same underlying data was referenced during Welcher's testimony regarding timing correlation with the Lexus Techstream data.
