I think there actually is video of a white Elantra traveling east toward Moscow, but the defense disputes that it's BK's Elantra. It's not in the PCA, but in the Supplemental Response to the State's Alibi Demand the defense says:
"Mr. Kohberger intends to offer testimony of Sy Ray, CSLI expert, (cell tower, cell phone and other radio frequency, curricula vitae is attached) to show that Bryan Kohberger's mobile device was south of Pullman, Washington and west of Moscow, Idaho on November 13, 2022; that Bryan Kohberger's mobile device did not travel east on the Moscow-Pullman Highway in the early morning hours of November 13, and thus could not be the vehicle captured on video along the Moscow-Pullman Highway near Floyd's Cannabis Shop."
There's no mention in the motion of the time stamp on this video, but it shows that the prosecution has additional video not included in the PCA. Floyd's is on the route that you would likely take going from Pullman to King Rd. It's kind of interesting that the defense chooses to dispute this video, but none of the ones that we know about in the PCA.
2:42am--BK's phone using cellular resources at his residence
2:44am--vehicle consistent with description of Elantra observed on WSU surveillance cameras traveling north on southeast Nevada St at northeast Stadium Way (not disputed--consistent with movements of phone)
2:47am--BK's phone used resources that provide coverage southeast of residence consistent with phone leaving residence and traveling south through Pullman
2:53am--white sedan observed traveling southeast on Nevada St in Pullman towards SR 270, which connects Pullman to Moscow (not disputed--consistent with movements of phone, but phone has stopped reporting to the network by this point)
Between 2:53am and 3:25am--video of white sedan traveling east on 270 toward Moscow (disputed by defense)
3:25am--white sedan westbound in 700 block of Indian Hills Dr Moscow (not disputed)
3:28am--vehicle westbound on Styner Ave at Idaho State Highway 95 in Moscow (not disputed--in at least one of these videos it appeared the vehicle was not displaying a front license plate)
3:29am--review of footage from multiple videos obtained in King Rd neighborhood showed multiple sightings of the suspect vehicle starting at 3:29am, including three passes by 1122 King Rd. Review of the video showed only a few cars enter and exit at this time (not disputed)
4:04am--seen entering a 4th time, driving eastbound on King Rd, stopping and turning around in front of 500 Queen Rd, then driving back westbound King Rd. Seen attempting to park or turn around in the road, made a 3-point turn at the intersection of Queen Rd and King Rd, then drove eastbound again down Queen Rd (not disputed)
4:20am--vehicle seen departing area of King Rd residence at high rate of speed and next observed traveling southbound on Walenta Dr (not disputed)
4:48am--the phone starts reporting to the network again, using services that provide coverage to Idaho State Highway 95 south of Moscow near Blaine, Idaho. Depending on where exactly that is, it's about 15 minutes south of King Rd--completely consistent with leaving King Rd at 4:20am, stopping somewhere to ditch whatever he needed to ditch, then turning his phone back on as he made the loop back home.
Why does that defense dispute that one video at Floyd's that shows him traveling east, but not any of the video actually near King Rd? It must be the weakest visually, but if the time stamp logically fits with the time the car left Pullman and time it's allegedly seen at King Rd, it's going to be hard to convince the jury it's not the same car.
