Suppressing the daughter's alleged motive to kill her parents leaves me a little puzzled. After all, how many possible motives could there be? After money/inheritance I can only come up with things like revenge, anger, jealousy, robbery, hatred, prevention of a secret being revealed, insanity, and of course a mercy killing. (Actually I am now surprised at how many I just came up with!) However a number of those don't seem to apply to the child of parents in their 90's, or if they did, it makes no sense that the murders were a year apart. Also, suppressing the motive so early seems to mean that LE didn't have any trouble in finding the motive. Curiouser and curiouser.
