Context: (CNN) -- They are some of the last thoughts of a serial killer, found on blood-soaked, handwritten and often poetic notes in his Alaska jail cell after he took his own life. 

"Speak soft in your ear so you know that it's true. You may have been free, you loved living your lie, fate had its own scheme, crushed like a bug you still die," Israel Keyes wrote. 

Keyes killed himself in December. He was in custody in the killing of barista Samantha Koenig, 18, whom he abducted from a coffee stand in Anchorage, Alaska, last February. Koenig was one of at least eight people Keyes admitted to killing, but he may have taken other lives, police have said. 

Keyes' notes were released by the FBI on Wednesday after they were cleaned up at the bureau's lab in Quantico, Virginia. They were found under his body, written in a combination of pencil and ink on a yellow legal pad, the FBI said in a statement. 

The bureau said the notes don't confirm any of his killings, add any new victims to his grisly toll, or offer any other clues that might help their investigation. It said an analysis showed no hidden messages or code in the four pages. 

But a read of them does give a glimpse into Keyes' mind, apparently describing how it felt to take a life and the disdain in which he held much of American society. 

"I looked in your eyes, they were so dark, warm and trusting as though you had not a worry or care. The more guiless (sp) the gaze the better potential to fill up those pools with your fear," Keyes wrote at one point.
