Thinking about how the murderer(s) accessed the home...
Is it possible that someone posing to be an interested party, went through the home (with a realtor) sometime close to the time of the murders, and unlocked that basement door? It would not have tripped any alarms or anything, just to have been unlocked and still shut.
If someone is inside the home and moving about, it would mean the home security system would have been disarmed, correct? So.. if the murderer knew that the basement door was already unlocked, he'd only have to wait until someone was inside the home, before gaining entry via that door.
Then.. just hide away in the basement somewhere until only the couple were home.
Maybe bring a backpack with some food/beverages to last awhile?
Obviously the cleaning staff did not access the basement on a regular basis, otherwise the bodies would have been found by the cleaning/gardener people!
