Bryan Kohberger is accused of stabbing four college students to death as they slept in their Moscow, Idaho home.

When the 28-year-old Ph.D. student was a teenager, he was a wannabe rapper who spit under the name Exarr.

In a 2012 Soundcloud track called 'Rise up instrumental – test", the then 17-year-old dropped some now disturbing bars.

“You are not my equal / You are evil but I’m devil/ End your life you get no sequel / Leave your loved ones crying like some seagulls."

Kohberger uses the Exarr username on his other social media pages.

If the Soundcloud page is determined to be Kohberger, its contents could be used against him in court.  However, given the time has passed between his rap career and his murder career it probably wouldn't be the strongest evidence.
