I don’t think he intended to kill that woman. However, it appears he has something on that phone he doesn’t want cops to see. Hmmm
Visits to Little St. James island for fun and games with with Jeff and Ghislaine? And their very young friends?
I’m guessing that he was playing around with her and fired intentionally not understanding the gun was loaded with active ammo.
As for the phone, he is probably just hiding his first call being to his lawyer.
pizza?
