I wonder if the neighbor was giving an approximate time of 1:00pm. Could it have been between 1:00 and 1:30? It only takes about 20 minutes to get to Walmart from the apartment using back roads. He could have been back around 1:20pm.
I don't know. The thing I question is his leaving to get the container. That was pretty risky considering KB was expected.
There are still a lot of unknowns, such as what happened with DB contacting KB to say she couldn't reach PB. Why KB didn't go straight to the apartment and whether KB had a key. Who all had keys. What time MJ was seen at Walmart.
Why no one was alerted to something being amiss when communication was cut off suddenly?
Things which I am sure will come out at trial......
