This would be the most logical. No need to bring a sick child into a daycare to spread germs further.
There absolutely were suggestions the death was faked or lied about. That only lessened when the obituary was posted multiple times.
The service was 21 days after the death, so the details aren't in the obituary. They were trying to come up with money for a service. Travel arrangements had to be made for out of state people.
It's even possible that two weeks notice was needed for some to get time off work. Maybe I've just had a lot more death in my life but I just see nothing weird about this scenario. We've delayed funerals for a month for all those reasons.
The sister lives in MA and Brittany lives in Texas. So if the picture is faked and Brittany didn't leave, did the sister fly to Texas to fake the picture? How did they both get the shirts?
If these people were smart enough to pull off a fake trip to a funeral, they would have "driven" so flight records couldn't prove them liars. Also they would have stolen actual plates for the car off of an identical car and/or dumped the car in a lake.
I guess I just don't understand the speculation on this point. It seems to be a huge stretch when there is only one named POI and it's not Mom.
Obviously, it's not up to me. I just think there are likely other things we could focus on. Search locations and such, like in Lucas' case.
