(NewsNation) — An inmate threatened the man accused of killing the four Idaho college students while he sat in a Pennsylvania jail cell, a source told NewsNation’s Ashleigh Banfield.

The source said Bryan Kohberger, 28, was housed in a cell with a glass door that offered little privacy beyond a blurred strip running along the middle of it.

“F— you, I’m going to kill you,” an inmate said with his middle finger raised to Kohberger as he sat in the cell.

Kohberger looked “creepy” according to the source, and did not appear remorseful or distressed in his five days in the Monroe County jail, but did talk to the people there.

When he was asked why he killed the four students, he responded, “I didn’t do anything.” When he was asked why he even went to Moscow, Idaho, he said, “The shopping is better in Idaho.”

Kohberger was dressed in a “suicide smock,” which is used to prevent detained individuals from killing themselves. He was able to shower each day while in prison, but he was not allowed to remove his leg shackles. His handcuffs, however, were released during the shower.

His request for vegan meals in the Pennsylvania jail was granted, including peanut butter and jelly, apple sauce, vegetables, beans, rice, cereal and maybe some potatoes, according to the source.

Kohbereger left the jail early Wednesday morning and is now in the Latah County, Idaho jail awaiting his first court appearance there.

Once that happens, state law allows the court to unseal the probable cause affidavit, which will have information about what led to Kohberger’s arrest.
