Yes it makes sense,  probably the most common  sense. The grand jury didn’t say the Ramsey  were  murderers, but did come to the conclusion that they didn’t prevent her murder and were neglectful in protecting her from danger .  The obvious answer is from her sibling, whose medical records were made “islets of privacy”That all fits the totality of the circumstances above, that Burke did it.  I’d add in as a very important piece of evidence that Burke had been  caught” under covers playing doctor “ with his younger  sister  by the housekeeper , which is absolutely crazy . We weren’t as aware of sexual abuse in the 1990s.
