He was 9 at the time.
Not very likely he killed his sister.
My theory is that Burke killed his sister, either accidentally or on purpose in a jealous rage. The Ramseys, in order to not lose their son, and now last child, to a lifetime of institutionalization, concocted the stupid ransome note and kidnapping story. That would explain their strange behavior on that day. It mirrored my own families' behavior whenever my brother would get in trouble with the law, even as young as six years old.............
You'd think (and hope) not. But, there was a case here in San Diego County this week where an 11 year old girl beat her 6 year old stepsister to death.
Oh, I see. If the BPD said something you agreed with, then they were telling the truth? Like clearing Burke? Otherwise, they were bumbling and inept liars?
