I'm no cell phone expert, and in fact I've never owned one, which will probably become abundantly clear from my questions and possibly false interpretations.
I noticed a few strange things on Joey's records. (see screenshot below - click to enlarge)
On a different date I noticed that when Joey was
at home (my interpretation based on string of calls to/from Fallbrook) the cell tower location is "
51132 Fallbrook". When he's
on the move, ie he's still in Fallbrook but his next call location is a different town, the cell tower location is "
51133 Fallbrook".
If this is correct, on the 4th,
4.18 pm his cell location is
51133 (
on the move close to home) - 3 minute call to Chase' phone (lasting until 4.21 pm).
4.25 pm (4 mins later) the house phone makes a call to Joey but it isn't on his call records, so his
phone is off and voicemail is left?
4.27 pm (2 mins later) his cell location is
51132 (
at home) when 2 x voicemails are retrieved (4 min. and 2 min.) so 4.27 to 4.33 pm. The second voicemail could be the 4.25 house call. The first voicemail could be if the house phone tried calling him at 4.18.
5.05 pm text from Summer's phone to Joey - not on his call records so
phone off?
5.47 pm (1 hr 14 mins after the voicemail retrieval) his cell is at
51132 (
at home) makes a +/- 3 min. call to Chase' phone.
8.28 pm (2 hrs 40 mins later) his cell location is
51133 (
on the move close to home) calls Chase +/- 1 minute, call doesn't connect.
Looking at this and using my interpretations I would say something happened to Joey before 4.25 pm. His phone off after calling Chase, the house phone making a call to him 4 mins after he connects Chase, and then 2 minutes later listening to voicemails at home. Summer must be at home to call him at 4.25, so she's not out. If he's there 2 minutes later there's no need to check the voicemails from her, he can ask what's up as he walks in the door. She texts him half an hour later and his phone is off again but he was there (if he was with his phone) at times either side of her text. He makes no work calls all afternoon.
I speculate 4.18 pm that is Chase getting near the home with Joey's phone. All the calls to Chase' phone are a ruse to try and show Joey is alive and going home, because he is a prolific phone user, voicemails are left. After the 5.48 call Chase' phone runs out of charge. Chase is parked in the driveway by 4.25 and Summer calls Joey to ask what Chase is doing outside. He sits in his truck and plays back the voicemails. After 4.33 pm he knocks on the door and Summer opens the door because she thinks something might have happened to Joey. He's there from 4.33 to just before 8 pm, less than 3 and a half hours. He's killed Summer and the children, put them in clothing containers, has cleaned up, dealt with the dogs and the fence, and then gathers business information from the office for his needs. When he gets back to his phone at 9.32 pm he puts it on charge to call Cathy.
The other thing I don't know is whether charged cell phones ping the tower when a voicemail is left.
