But he could have easily left a door open which would implicate someone else. There was no need for him to have invented a call.....Maybe he was stupid, unintelligent or he did not do it?
Trying to implicate an unknown outsider breaking in to rob would have involved raising questions with no logical answer, ie WHY would such a person feel the need to turn a burglary into slaughter and leave empty-handed. A burglar, caught in the act, is surely going to think FIRST, of escape, NOT hanging around to slaughter the entire family, LEAST of all, two sleeping children. WHY would random burglar risk turning a rap over the knuckles and a fine -if caught- into a life stretch.
Trying to make it look like random burglary gone wrong would have involved Jeremy in getting into the mindset of what he believed would be the MO of a random burglar but there was nothing to suggest that anyone had been looking for valuables. No draws opened. No contents strewn. No missing objets d'art. No missing jewellery.
I imagine Jeremy saw his plan as being perfect in its simplicity..................and it actually WAS. His mentally ill sister had had a violent episode and got hold of a firearm, during which his father had been able to make a frantic call to Jeremy for assistance. What could POSSIBLY go wrong?.........................
