I haven't seen discussion of Kohberger's long road trip on the afternoon/evening of November 13, but the threads are moving so fast. Kohberger's travel that day are documented in the PCA beginning at the bottom of page 16).
To summarize, Kohberger drove east at least as far as Johnson, Idaho, about 100 miles from Pullman, to the area around the Nez Pearce - Clearwater National Forest. His phone pinged and he was spotted on surveillance camera at several locations in Clarkston, WA. He left Albertson's grocery store at 1:04. It's about 75 miles to Johnson, an hour and a half drive. The next pings detailed in the PCA are 4.5 hours later: in Johnson, Idaho between 5:32 and 5:36. The phone then stopped connecting to the network until 8:30.
It's not clear where the 8:30pm ping occurred. This sentence (from page 18) confuses me. BBM.
The 8458 Phone then stops reporting to the network from approximately 5:36 p.m. to 8:30 p.m. That is consistent with the 8458 Phone being the area that the 8458 Phone traveled in the hours immediately following the suspected time the homicides occurred.
What does the sentence in bold mean? Does it mean BK was in Moscow at 8:30? On the route the indirect route he used immediately after the murder (driving south on 95 toward Genesee, then west to Uniontown, Idaho; then north to Pullman, Washington.)
As for the purpose of the trip, it seems to me that Kohberger drove east into a remote area to clean the car thoroughly and dispose of evidence, perhaps using supplies he purchased at Albertson's. He may have burned the clothes he'd worn to commit the crime. I don't think he would have thrown the knife somewhere where it could not be retrieved, like a river. I think he carefully selected a place to hid it where he retrieve it eventually. I wonder if the phone turning on for 4 minutes only at 5:32 was Kohberger getting the GPS coordinates or taking photos of features near the location he could use as markers. JMO>
