Authorities seized dozens of items — including three knives, a .40 caliber gun, and a note — from the home of Idaho killings suspect Bryan Kohberger's parents in Albright, Pennsylvania, according to search warrant records released Thursday.

Multiple pairs of black gloves were also found, along with three .40 caliber magazines, a "green leafy substance" in a green container, a pocket knife, and a black mask, according to the warrant return.

The court documents list a "note from Bryan to Dad," but don't reveal what the note said.

A separate search warrant released Tuesday said that police also discovered four medical gloves and a collection of clothing at the same home.

Several DNA swabs were also taken from Kohberger, according to the documents.

Additionally, police uncovered a shovel, goggles, and more gloves from his car, the search warrant revealed.

Kohberger — a 28-year-old graduate student — has been accused of killing four University of Idaho students in November.

The four students were found dead in an off-campus home on November 13. Three of the victims lived there with two other surviving roommates. The fourth victim was the boyfriend of one of the slain girls.

One of the surviving roommates told police that in the early hours of November 13, she heard and saw a man wearing a black ski mask leaving their home.

Police believe Kohberger drove in his 2015 Hyundai Elantra from Washington state to his parents' house in Pennsylvania for winter break before officers arrested him there, according to a probably cause affadavit obtained by Insider. He was then extradited to Idaho where he awaits trial.

Kohberger was a graduate student studying criminology at neighboring Washington State University, which is only a 10-minute drive from the University of Idaho. Police are still trying to figure out a connection between Kohberger and the slain students. People reported that Kohberger had tried to slide "into one of the girls' DMs" on Instagram.

The lawyer for one of the slain students previously told Insider that they had no connection with Kohberger and said "no one knew of this guy at all."

The New York Times reported that Kohberger was investigated by Washington State University for his behavior toward female students.
