As the search continues for the suspect who killed four University of Idaho students as they slept, cops are asking for the public's help in locating a white 2011-2013 Hyundai Elantra.

Police say the vehicle was near the off-campus home, and it's possible that whoever was in the car may have critical information. In the meantime, officers have begun to box some personal items to return to the victims' families.
