BBM. I find it ODD that SA and BD claim to not have a computer but have jump drives and flash sticks/drives. BD had stated that Hailey had some flash drives for school, well why would Hailey have flash drives for school if they didn't have a computer in that house?
I do not know what LE has or does not have as far as evidence is concerned. I don't know that LE is going to announce publicly what evidence that they may or may not have against their POI so therefore I do not know if it is contrary or not.
With what I do know from statements made by BD and SA to the media, I am convinced.
They didn't have a computer, but BD would have had access to one at work, while SA used the one at his grandmothers house.
Jump drives are used to transport files from one computer to another, in their case it would have been their primary data storage mechanism since they didn't have their own computer.
