Forensic team reveals Kohberger's panicked phone activity before Idaho murders arrest

The car was still on his mind in the hours before his arrest, according to the Barnharts.

"If you weren't the bad guy, you wouldn't care, but he was scrambling, and he thought the police were on him," Jared Barnhart told Fox News Digital. "And they were. They were at that point."

According to phone data reviewed by the Barnharts, Kohberger did the following during the late-night hours of Dec. 29, 2022:

"Literally the pressure of, 'Oh, look, they're really talking about my car,' caused...within 15 minutes of behavior, him trying to clean it and get rid of it," Jared Barnhart told Fox News Digital. "Just not normal."

At around 1:30 a.m. on Dec. 30, police swarmed his parents' house and arrested him.

But detectives have maintained that even if they didn't have the sheath, they would have found Kohberger by hunting down leads connected to the suspect vehicle, which appeared on surveillance cameras coming and going from the crime scene. 

All but Kernodle are believed to have been asleep at the start of the 4 a.m. home invasion attack.

He received four consecutive sentences of life without parole, plus another 10 years.
