MOSCOW, Idaho — Law enforcement towed several vehicles away from the scene of a quadruple homicide near the University of Idaho on Tuesday, more than two weeks after four students were stabbed to death at the off-campus residence. 

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

The vehicles are just part of a massive trove of evidence that law enforcement continues to sift through 16 days after the grisly murders.

The vehicles were taken to a city-owned maintenance shop a couple of miles away from the home. 

Five people lived at the residence, including three of the victims – Kaylee Goncalves, Xana Kernodle, and Madison Mogen.

Another victim, Ethan Chapin, was dating Kernodle and was staying the night on Nov. 13. Two other roommates who lived at the three-story house were not injured in the attack. 

Police believe that all four victims were stabbed multiple times by an unknown assailant between 3:00 and 4:00 a.m. after returning home from a night out. 

Goncalves had just purchased a Range Rover and returned to school two days before she was killed, according to her mom, Kristi Goncalves. 

"She just bought a brand new vehicle for herself, her first vehicle," Kristi told Fox News' Lawrence Jones. 

"She went home Friday to literally go show off her new vehicle. She was like, ‘Maddie has to see my new ride. Like, she has to see this.’ And she was talking to Maddie the whole time going back and forth between the car she was buying."

Idaho State Police Forensic Services is "doing much of the forensics analysis" and have scientists "working 24/7 in the lab" to process the evidence, Snell previously said. 

Detectives have received more than 488 digital media submissions and more than 1,000 tips, but are still appealing to the community for additional information.

"To assist with the ongoing investigation, any odd or out-of-the-ordinary events that took place should be reported," local police said. 

"Your information, whether you believe it is significant or not, might be a piece of the puzzle to help investigators solve these murders."

Authorities have not identified a suspect or located a murder weapon.

Snell said that he isn't sure when police will release the crime scene as a whole, calling it a "complex process." 

Police cordoned off the home on the day of the murders, then expanded the crime scene last week to include a parking lot and forested area behind the residence.
