A former Federal Bureau of Investigation detective says that hair follicles of the suspect in a quadruple homicide on Nov. 13 near the University of Idaho may lead authorities closer to making an arrest as forensic testing of evidence is beginning to be shared with authorities.
Ethan Chapin, 20; Xana Kernodle, 20; Madison Mogen, 21; and Kaylee Goncalves, 21, all University of Idaho students, were killed during the early morning hours of Nov. 13 between 3 and 4 a.m. and police have not yet identified a suspect. Police say the victims were stabbed multiple times, with some showing signs of defensive wounds based on an autopsy conducted by the Latah County Coroner.
Authorities recovered over 113 pieces of "physical evidence" from the crime scene, which was sent to the Idaho State Police Forensic Services crime lab. Idaho State Police Communications Director Aaron Snell told Fox News Digital on Wednesday that investigators have begun to receive results from forensic testing of some evidence.
Former FBI special agent Jonathan Gilliam told Fox News Digital that if the suspect left hair follicles at the crime scene, it could help lead investigators to a potential suspect.

"If [the attacker is] standing over them and he's stabbing ferociously, then he could have hair follicles that could fall off, his own skin could shed on there, if he cut himself and it bled on her. If they do their collection diligently, then they will find those particles of DNA, and then they'll have that," Gilliam commented as authorities begin to receive results from forensic testing.
Gilliam noted that DNA testing is a "very detailed exercise" that takes time to process, adding that authorities are likely working through a process of elimination.

"So many people were in there, the fact that they're young people means the DNA may not come back to anything," Gilliam said. "But with a house like that and you're talking about 10 to 40 people a week and even more, there's a tremendous amount of of DNA that is repeated. Already right there, you're looking at 50 different people, strands of DNA."
"They're going to get those, separate those, and then try to see if they can place those with somebody," he added.

Chapin and Kernodle were at the University of Idaho Sigma Chi fraternity house before returning to the King Road home at 1:45 a.m. on Nov. 13, police say.

The 911 call was made at 11:58 a.m. on one of the two surviving roommates' cell phone. Police say that the two roommates didn't wake up until later in the morning on Nov. 13.
While police haven't yet identified a suspect in the attack, authorities remain confident that the attack was targeted.
"Our clarification last night directly addressed comments made by Latah County Prosecutor Thompson, who said the suspect(s) specifically looked at this residence, and that one or more of the occupants were undoubtedly targeted. We remain consistent in our belief that this was indeed a targeted attack but have not concluded if the target was the residence or its occupants," a statement from the Moscow Police Department to Fox News on Thursday read.
