These crimes have such a tight schedule.
Somewhere between 9pm and 9:30pm, the murders are committed.
Presuming this is not random, the killers know that AM and MM are residing at Moselle. They would have no idea when AM might turn into the driveway. As it is, he may have only missed being there by 30 minutes. So, I can’t imagine much attention could be paid to cleaning up, wiping off weapons, destroying evidence.
With two people dead in an area that could well have been visible from the driveway…especially with headlights… I think they’d get out of there as quickly as possible.
Depending on where MM’s phone was found, they may have had to exit out that same narrow driveway where AM could be pulling in at any moment. If they go that way…they then ditch the phone on Moselle Rd. and off they go. All before 10pm…when AM arrives home.
Now AM allegedly arrives home and it is ‘around’ 10pm and he finds the horror.
He begins making phone calls…in what order we don’t know. But we know he had trouble reaching JM, had to keep calling, finally calling the sister-in-law’s phone. And, of course he calls police at 10:07 pm.
When he calls RM who lives 15 minutes away, RM comes immediately, but he says the police were on the scene already and the bodies already recovered, so it had to be well after 10:28pm.
The initial LE arriving around 10:28pm almost immediately declares the area secure for the medics…which is good, because more M family members are arriving.
All this action in one hour or…at the most around 90 minutes…from murders to secure scene. From maybe 9pm…to 10:28pm.
