The suspect accused of murdering four University of Idaho students at an off-campus home in November gave the car he drove to allegedly commit the crimes a thorough cleaning before he was arrested.

A law enforcement source told CNN that Bryan Kohberger, 28, was observed wearing surgical gloves multiple times and cleaning the interior and exterior of his car.

During the four days of surveillance placed on Kohberger's family home in Pennsylvania, the insider was briefed on the investigators' observations. The source was told Kohberger "cleaned his car, inside and outside, not missing an inch."

While under surveillance, Kohberger also reportedly once left his family's home at around 4 a.m. to place garbage bags in his neighbors' trash receptacles.

Investigators later collected those items as well as garbage placed in the Kohberger family's trash bins. The items were then sent to the Idaho State Lab for analysis.

On Dec. 30, 2022, the Pennsylvania State Police SWAT team broke down the door and windows of the home as a tactic known as a "dynamic entry," which is used to arrest "high-risk" suspects.

After waiving extradition, Kohberger made his first court appearance in Idaho on Thursday.

At the hearing, Kohberger's attorney asked the court to consider setting a bond, but the judge rejected the request citing an Idaho code that doesn't allow bond for first-degree murder, Idaho Statesman reports.

Kohberger is facing four counts of first-degree murder and one count of felony burglary following the deaths of Kaylee Goncalves, 21; Madison Mogen, 21; Ethan Chapin, 20; and Xana Kernodle, 20, on Nov. 13, 2022, at an off-campus home in Idaho.

Approximately 65 people were present for the hearing, including the victims' families. Shannon Gray, an attorney for Goncalves' parents, read a statement outside the Latah County Courthouse after the hearing.

"It's obviously an emotional time for the family — seeing the defendant for the first time," Gray said. "This is the beginning of the criminal justice system, and the family will be here for the long haul."

At the time of the murders, Kohberger was a Ph.D. student at Washington State University. He is expected to return to court on Jan. 12 for a status hearing.
