Newly released police body camera footage shows the University of Idaho murder suspect and his father discussing a Washington shooting during a traffic stop in Indiana

• Police in Indiana released video of the man accused of murdering four University of Idaho students.
• In the Dec. 15 footage, the man and his dad can be heard talking about a shooting in Washington.

New police body camera footage shows the man accused of killing four University of Idaho students and his dad talking about a Washington shooting during a traffic stop in Indiana last month.

The footage, released on Tuesday by Indiana's Hancock County Sheriff's Department, shows the first of two times in which the 28-year-old suspect was pulled over on December 15 in Indiana for allegedly tailgating in a white Hyundai Elantra sedan.

"You were right up on the back end of that van. I pulled you over for tailgating," an officer can be heard telling the suspect, according to the footage, which was obtained by Insider.

The suspect's father told the officer that the pair was coming from Washington State University where the suspect is a criminal justice graduate student and teacher's assistant.

The suspect and his dad then proceed to tell the officer about a shooting incident that happened near the school that day and how a "SWAT team" was involved.

"There was a mass shooting and everything," the father says, prompting his son to interject, saying, "We don't know if it was a mass shooting," according to the footage.

Authorities in Pullman, Washington, shot and killed a man during a police standoff on December 15 — and the two appeared to be talking about that incident.

Additionally, during the traffic stop, the suspect's father told the officer that he and his son were headed to Pennsylvania and were "slightly punching it" because they had been driving "for hours."

The officer let the pair go with a warning.

"Do me a favor and don't follow too close," the officer told them.

Minutes later, the suspect and his father were stopped again, this time by Indiana State Police, for allegedly tailgating a tractor-trailer. They were again let off with a warning.

The suspect was arrested in his hometown of Albrightsville, Pennsylvania, last week on first-degree murder charges in connection to the November 13 stabbing deaths of four college students in the small city of Moscow, Idaho.

The man lived just miles away from the rental home where victims Kaylee Goncalves, 21, Madison Mogen, 21, Xana Kernodle, 20, and Ethan Chapin, 20, were killed likely while they slept, officials have said.

In his first court appearance Tuesday afternoon, he told a Pennsylvania judge that he would voluntarily return to Idaho to face the murder charges.

The suspect was expected to arrive in Idaho on Wednesday. An attorney who represented him at his extradition hearing previously said that the suspect believes he will be "exonerated."
