After discovery that he was alive, no one has posted a summary of what exactly happened to him. It's unclear with some saying he was captured, but no details. Can someone either summarize or point to the video/post where CRP explains it?
Also, the accusation that someone opened his iphone XR without his help is very weird. The FBI had trouble opening much older phones, and supposedly this was done by Ukranians in the field? I don't believe anything is unhackable but I also don't think it's such a fast/simple process unless he used a basic password like 1234.
That was almost ten years ago. Now they can do it easily especially with glow help.
Alternatively you just use the facial recognition unlock or beat/sleep deprive them until they crack and give you the passcode
