Long before confessing to killing four college students, Mr. Kohberger wrote of being depressed as a teenager and became addicted to heroin.

As the world continues to process the horrifying crimes of Bryan Kohberger — the man convicted of murdering four University

Bryan Kohberger lost over 100 pounds to escape bullying, and then became a killer. Research reveals the dangerous psychology that can turn some victims into predators.

Prosecutors say they wanted to spare the families of four University of Idaho students killed in November 2022 by agreeing to a plea deal that would see the confessed killer avoid a possible death sentence.

Prison experts discuss how Bryan Kohberger's admission to the Idaho student murders might make him vulnerable in prison, where inmates serving life sentences have nothing to lose.

The plea deal that spared Kohberger's life required him to admit the elements of the crimes he committed, but it didn't force him to provide a narrative or say why he did it. That has raised questions about whether prosecutors could have or should have insisted on a full confession — including motive — as a condition of the deal.
