Or Joey was driving and couldn't answer? Or didn't hear his phone?
I miss calls from my home many times just walking round the supermarket when the kids call me to add something to the shopping list.
Just to explain, my point wasn't that he didn't answer, it was that the call was made from the landline so I think there was a problem at home, meaning Summer was separated from her cell phone and either tried to make a call to him from the landline or possibly told Gianni the numbers to dial if she was restrained.
It comes back to me thinking she was tied up with the blue painters tape. I think it's strange because she was using her cell phone earlier and also Joey's Voicemail was checked two minutes later - so if Merritt had the phone he may have been listening to see if the message said anything about calling the police.
I like the theory he loosened a fence panel that he could come back to without being observed by neighbors and so I think he was outside for a while and that could be when she tried to call Joey but he caught her.
If that is him leaving the house and then a cheque was printed 9 minutes later he had a reason for not printing the cheque while his truck may have been picked up by neighbors' surveillance cameras or seen by neighbors arriving and/or parked outside. The truck was backed into the drive because it emerges headlights first, so in the dark and close up to the house he could load their bodies into the back without being seen but he knew once he started the engine up and put the headlights he may be observed driving away. Maybe he even purposely made the loud noise that Mitchley heard when she put her porch light on, so that neighbors would observe him leaving. It was only moments before the truck left and I doubt it was screams because I think she would have remembered wondering whether to call 911, plus I think they were already dead by that time and loaded in the truck.
I think he opened the office window before leaving, then drove around the corner into Avocado Vista, parked up by the entrance to the vacant plot of land that runs behind the rear fences of Avocado Vista Lane homes, and walked back to the fence he had loosened for entry. The timing seems perfect for that.

It means he was at the house from around 4.20 until 7.47, which is 3 and a half hours. Time to restrain Summer, maybe to get passwords from her, possibly with the idea of raping her before he killed her, mess around with the fence, sort out the dogs with food to keep them quiet, give the children popcorn to keep them quiet, poke around in the office for stuff he might have wanted on the computer or in paperwork, rape Summer, kill her and the children, clean up, paint a bit, waiting for dark at 6.47 pm to load their bodies in the truck, check the house over a bit more, find something to wrap up Joey's body with when he got back to him because he wouldn't want his blood in his truck, and go. I think he wanted to torture Summer before he killed her. I also think they were all dead in the truck because he wouldn't leave them alone to make noise if he was going back to the house, and the child backpack was just something Joey put on to comfort himself or because it was another thing he told him to do to keep him occupied, he did want it to appear that the family left on a trip. I think he took the car seats from the Dodge.
