Kip Kinkel was sentenced to 111 years in prison for the murder of his parents and the murders and attempted murders of students during his rampage attack in May, 1998. In 2002 he appealed his sentence. The court record includes a summary of the details of his attacks as well as information provided to the court by mental health professionals.

As noted in this document, Kinkel requested “that the judgment of conviction be set aside and the sentences vacated. In support of that request, petitioner contends that, among other things, he had received constitutionally inadequate assistance of counsel during the plea negotiations, that his acceptance of the plea agreement was not knowing and voluntary, and that the plea agreement should not have been accepted without the consent of his guardian ad litem.” The court did not support Kinkel’s request. 

This is a transcript of Kip's confession to Detective Al Warthen shortly after his rampage attack on May 21, 1998.

Prior to his rampage, Kip attended therapy sessions with Dr. Jeffrey Hicks from 20 January through 30 July 1997. This document contains his records of the therapy sessions.

This document contains excerpts from court testimony on Kinkel's mental status provided by four mental health professionals: Dr. Orin Bolstad, Dr. Richard Konkol, Dr. William Sack, and Dr. Jeffrey Hicks.

This document contains several pieces of Kinkel’s writings.

After Kip's attack, his sister wrote a letter to the judge about her brother as she knew him.
