Police confirmed that a vehicle shown on surveillance footage driving near the crime scene at the time of the killings where the four Idaho students were murdered is what led authorities to identify the killer as suspect Bryan Kohberger.

28-year-old doctoral student in criminology at Washington State University Bryan Kohberger was caught in Pennsylvania last week, and was transferred to Idaho where he is being charged with four counts of first-degree murder and one count of felony burglary.

The murders happened on November 13 when the three girls who were housemates were found stabbed alongside one man who was staying over at the off-campus house in Moscow, Idaho. 

The students, Kaylee Goncalves (21) Madison Mogen (21) Xana Kernodle (20), and Kernodle’s boyfriend, Ethan Chapin (20) were likely to have been asleep when they were stabbed multiple times, detectives said. Autopsies revealed that some of them carried defensive wounds, indicating they tried to protect themselves as their killer struck.

After the police identified the vehicle as a 2015 Hyundai Elantra, they were able to trace it as it was registered under Kohberger's name. “This is a residential neighborhood with a very limited number of vehicles that travel in the area during the early morning hours,” Moscow Police Cpl. Brett Payne stated in an affidavit.

“Upon review of the video there are only a few cars that enter and exit this area during this time frame.”
 
Further, police was able to obtain DNA evidence from trash at Kohberger's family home in Pennsylvania as it matched the DNA traced from a knife sheath found at the crime scene. 

Kohberger is due for a status hearing on January 12 in Idaho and as of now, no motive has been revealed as to what caused Kohberger to commit this stabbing spree.
