Investigators hunt for missing white Hyundai as key evidence in murder of Idaho college students

Police in Moscow, Idaho, say they are actively searching for a vehicle that may hold "critical" information regarding the killing of four college students in the college town last month, with the northern U.S. border also under surveillance for the vehicle. 

The Moscow Police Department said Thursday detectives "are interested in speaking with the occupant(s) of a white 2011-2013 Hyundai Elantra, with an unknown license plate."

"Tips and leads have led investigators to look for additional information about a vehicle being in the immediate area of the King Street residence during the early morning hours of November 13th," when the killing took place, the department also said in a press release.

"Investigators believe the occupant(s) of this vehicle may have critical information to share regarding this case," police added.

A Customs and Border Protection spokesman, meanwhile, told Fox News that border officials are keeping an eye out for the vehicle. 

"Our ports of entry out that way are aware of it and will be keeping an eye out for it," the spokesman told the network. 

Moscow is located a little over 150 miles from the Canadian border.
