I know others have been saying they didnt know it was BK u til Dec 19th. However, its good to keep in mind a few prior dates. This is from my timeline.
Nov 29, 2022 BK identified as owner of white Elantra by WSU police.
Dec 7, 2022 Police appeal to announce to public their interest in talking to driver of White Elantra seen in immediate area of crime at time of crime.
Dec. 19, 2022 Moscow Police Chief James Fry sent Jenkins a message on Dec. 19, 2022, requesting that he come to the Moscow station the following day. Jenkins assumed it would be another briefing, so he was surprised to be led into a room with about 20 to 30 people, including members of the FBI and Idaho State Police, he said. They informed him that they had identified a suspect using DNA found at the scene. That suspect, his colleagues told him, was a student at WSU named Bryan Kohberger. “It took me a minute, and then I said, ‘You know that name is very familiar. I think I’ve talked to Bryan Kohberger before."
As early as Nov 29th they had a name. But, they need the results from the dna.
