IDAHO MURDERS: SLAIN STUDENTS' CARS TOWED FROM CRIME SCENE TWO WEEKS AFTER GRISLY ATTACK.

Cars possibly belonging to the four slain University of Idaho students are towed to impound for investigation by the police.

Idaho State Police Communications Director Aaron Snell told Fox News Digital the vehicles were being transported to "secure long-term storage" for "further evidence gathering." The vehicles were taken to a nearby maintenance shop owned by the city.

During an interview Wednesday, Snell said that the cars were previously searched.

"I believe that all of those vehicles had previously been searched, and they're still part of the crime scene," Snell said.

Ken Mains, a former FBI detective, told Fox News Digital the vehicles likely weren't towed until two weeks after the killings because there was likely little thought they had something to do with the crime.

A Range Rover believed to be Kaylee Goncalves' and several other cars of unknown ownership were towed from the scene of the quadruple homicide in Moscow, Idaho.

Former FBI special agent Jonathan Gilliam told Fox News Digital investigators are going to want to look for fingerprints and DNA evidence inside the vehicles

Gilliam said if the killer is someone the students knew, "there's a chance that they had been in that car." 

The former FBI special agent said he thinks investigators waited too long to tow the vehicles because the cold weather may have broken down potential fingerprint evidence
