Bryan Kohberger's Amazon shopping records and "click activity" are damning for his defense, after he allegedly bought a Ka-Bar knife before the Idaho murders.

A flurry of court documents have been filed this week in the case of Bryan Kohberger, the man charged in the killings of four University of Idaho students in late 2022.

Kohberger's sedan was captured by a plate reader in Loma, Colorado, on Dec. 13. The car was stopped by law enforcement in Hancock County, Indiana, on Dec. 15. On Dec. 16, the car was seen on surveillance video in Albrightsville, Penn.
