Photos taken outside the home where four University of Idaho students were stabbed to death earlier this month show an eerie scene left behind after several cars were towed away.

Five cars, which presumably had not been moved since the Nov. 13 attack, left gave-like looking rectangular sections of concrete surrounded by accumulated snow when they were removed.

Police have not yet confirmed that the cars belonged to victims Kaylee Goncalves, Xana Kernodle, Madison Mogen and Ethan Chapin. The cars were taken to a city-owned maintenance shop several miles away.

Idaho State Police Communications Director Aaron Snell told WHD News Digital the cars were being taken to "secure long-term storage" for "further evidence gathering."

Two days before she was killed, Goncalves purchased the Range Rover seen towed away from the home, according to her mom, Kristi.

Kristi told WHD News' Lawrence Jones that Goncalves went back to the Moscow, Idaho home to show Mogen her new car.

Goncalves, Kernodle, Mogen and two other girls, who were not injured, lived at the off-campus home. Chapin, Kernodle's boyfriend, was staying the night when the deadly attack took place.

Police believe all four victims were stabbed multiple times between 3 a.m. and 4 a.m. by an unknown assailant after returning home from a night out.

The home was cordoned off the day of the murders. Police expanded the crime scene last week to include the parking lot and a forested area behind the home.
