I agree; whoever harmed Jeff planted his boots by the ocean in order to lead everyone to believe that he had fallen into the ocean either by accident or suicide. The perp might have even thought that people would give up on finding Jeff rather easily if they thought he was in the ocean. I think the same of the cell 'phone: It has been reported (
http://www.hawaiipolice.com/missing-jeffrey-meek-update-11-14-14) that someone in the family purportedly pinged Jeff's cell 'phone using a website. I, personally, don't think it is in the vicinity of the cave. One thing that I still think about is the fact that -according to Jeff's mom via MSM- the night before he went missing, she called Jeff to surprise him with the news that she would be visiting him and his family for Thanksgiving. At first I didn't think too much of it (it appears that Jeff and his mom talked to each other quite often, even more than once a day at times), but I now believe it is possible that someone found this out and freaked out, so to speak; Jeff's mom herself has said she spent some time with Jeff earlier this year going over his company's accounting records ....
