Though the motive behind Bryan Kohberger's violent attack remains unknown, the former police chief says "new information could come out still."

The former criminal-justice doctoral student convicted in the 2022 stabbing deaths of four Idaho college students appeared in court for sentencing on Wednesday with uncertainty surrounding whether he would disclose a motive for the killings.

Bryan Kohberger received four life terms after the victims’ families and friends faced him in court. He declined to speak, and investigators said they remained mystified by his motives.
