Yellow Dog, All very good questions that need answers...
I have never understood why on a sunday the girls had not eaten in 12 hours.....it's very unusual in my family to not have breakfast and lunch on Sunday.
I have also thought T. sleeping in a sleeping-bag seems suspicious, as if a way to protect herself. Now and then seems o.k... BUT all the time, seems strange to me!.....Had some other person moved into her bedroom?.
No one has said WHO was at the P. house that Sunday.
Something could have happened and the girls was waiting for Rose, possibly because someone very negative was at the P. house.
Could the killer been at the P. house that day looking for someone or something ???
Another possibility is, someone at the P. house got into a bad argument/fight/maybe drugs involved/,
with a male, and that person, upon leaving the P. house mad, shot the girls to get back at the person they were arguing with.
I question WHY P.P. lied about getting the cell phone from Taylor's pocket and making the 911 call, the reason behind this should be looked at more closely.
Maybe he was 'covering' for checking T.'s Purse for 'something' ....jmo
