Bryan Kohberger says jail life’s already a nightmare — claiming inmates gained’t cease hurling threats and crude sexual taunts his method … and now he’s begging for a switch.

In a handwritten word, the convicted killer pleaded with officers to get him out of Idaho Most Safety Establishment’s J-Block — only a day after being transferred there on July 29. Folks was first to report on the July 30 word.

Kohberger insists within the word he is not a part of any latest chaos — citing “flooding/hanging” — however claims he is getting slammed with “minute-by-minute” threats and harassment, saying he desires out of J-Block ASAP.

A couple of days later, he reportedly slipped a guard one other word claiming inmates have been screaming graphic sexual taunts at him … together with, “I’ll b*** f*** you” and “The one a** we’ll be consuming is Kohberger’s.”

A guard’s descrpiton of the incident reportedly confirms inmates have been spewing nasty language — however the guard couldn’t say who mouthed off. Nonetheless, regardless of his complaints, Folks says jail officers determined Kohberger was “protected sufficient” to stay it out in J-Block … for now.
