Well, we know he wasn't "right at the DMV on the 18th." If he had been, he would have gotten his WA plate that day rather than it being mailed to him about 3 weeks later in Dec (as verified in the link above as well as in lots of MSM links I've posted such as this one Idaho murders: Bryan Kohberger changed license plate five days after student slayings )His tag and title was registered and still current in PA.
The murders took place late Sat early Sun 14th and he was right at the DMV on the 18th. Possible not related, not probable to me.
Bryan C. Kohberger, a suspect in the murders of four University of Idaho students, changed the title of his white 2015 Hyundai Elantra five days after the stabbings took place.
According to a public records request filed by KTVB, Kohberger, 28, applied to transfer the title of the Elantra from the Commonwealth of Pennsylvania, which was issued on April 20, 2022, to Whitman County, Washington, on Nov. 18, 2022. It was then issued Dec. 5, 2022. Records show the vehicle was also registered.

Here is the DMV link stating he would have gotten the plate that day had he gone to the DMV in person rather than handling the matter online and by mail. (The title had to be mailed.) WA State Licensing (DOL) Official Site: Register your vehicle
He also had to get a WA driver's license before registering his car in WA. DL fees in WA are very high. His PA plate was good until the end of Nov (not April. See PCA for verification of Nov expiration.) So it's not so clear that he was choosing to be foolish financially by waiting until Nov.
