While Idaho investigators are searching for a possible person in a white sedan caught on security camera near the crime scene of the University of Idaho quadruple murders, bodycam footage released Thursday shows three others near the crime scene, pulled over for a sobriety test.

As CrimeOnline previously reported, police asked anyone who owns or knows of someone who owns a white Elantra — a 2011-2013 model — to send that information to the tip line at 208-883-7180, email to tipline@ci.moscow.id.us, or upload digital media at fbi.gov/moscowidaho.

Police again stressed that they have not identified a suspect in the November 13 murders of Madison Mogen, 21; Kaylee Goncalves, 21; Ethan Chapin. 20; and Xana Kernodle, 20.

Now, ABC News has obtained police bodycam footage from the night of the murders that shows a police stop around 3 a.m., which, according to police, was around the time the students were killed. Police pulled over a car for a sobriety test near the off-campus rental where the murders occurred.

Although police released the suspects and said the stop was unrelated to the case, analysts told ABC News that the bodycam footage could still be used as part of the investigation.

“It can be used from a historical standpoint. That information could potentially become relevant later in the investigation; you just never know,” former FBI agent Brad Garrett told ABC News.

Meanwhile, the investigation continues.

According to Moscow police, two of the victims were found on the second floor, and another two were found on the third floor of the house, which is built into a hill off campus. Two roommates who were on the first floor were not attacked by the intruder, and police say they do not believe the surviving roommates had anything to do with the murders.

“We believe someone has information that will add context to the picture investigators are creating of what occurred. … Your information, whether you believe it is significant or not, might be one of the puzzle pieces that help solve these murders,” Moscow police said Monday.

Authorities previously said a sharp-edged knife was used during the attacks.
