Bryan Kohberger is now fighting to block key evidence including surveillance footage, his Venmo and Paypal activity, and his student records from his capital murder trial.
In a new motion filed Monday, the accused killer's defense attacked a trove of evidence in the prosecution's case, arguing that much of it is too broad and its relevance unclear.
As part of this, the defense took aim at surveillance footage from the night of the murders on November 13 2022.
The footage, which has been circulating online but has not been released by authorities, was captured on an apartment complex on Linda Lane close to the crime scene at 1122 King Road in Moscow, Idaho.
Prosecutors have previously revealed that a white Hyundai Elantra - matching the description of Kohberger's vehicle - was spotted circling the student home at around 4am on November 13 2022. The vehicle was then allegedly seen speeding away from the scene at around 4.20am - minutes after the slayings.
But Kohberger is arguing the footage prosecutors want to enter as evidence is 12-and-a-half hours long making it impossible for his defense to wade through.
The defense is also pushing back against several other surveillance videos taken from local businesses, including from Bagel Shop, Café Artista, Sunset Mart and Floyd's Cannabis Co.
Footage from the Corner Club - where victims Madison Mogen and Kaylee Goncalves spent their last night out together - and footage from the Grub Truck - where the two best friends stopped to get a late-night carbonara before heading home - is also under scrutiny.
