[1][2] In January 2005, Scott Cheever shot and killed Greenwood County Sheriff Matthew Samuels at the residence of Darrell and Belinda Coopers in Hilltop, Kansas.
At trial, Cheever asserted a voluntary intoxication defense and argued that the methamphetamine use rendered him mentally incapable of the premeditation required for murder.
The prosecution sought to bring the interview transcript into evidence to impeach Cheever's testimony regarding the order of events at the Coopers' residence, which the court allowed.
The Kansas Supreme Court held that the admission of the government psychiatrist's testimony into evidence violated Cheever's Fifth Amendment rights.
Not allowing this would "undermine the adversarial process" and permit a defendant to provide "a one-sided and potentially inaccurate view of his mental state" at the time of the crime, through an expert.
