The death penalty against Scott Cheever now stands in the murder of Greenwood County Sheriff Matt Samuels.
The U.S. Supreme Court on Wednesday overturned a Kansas Supreme Court decision from last year which was poised to lead to a new trial had the U.S. court not acted as it did.
Last year, the Kansas high court ruled Cheever's constitutional rights were violated when the state used a court-ordered mental evaluation from a trial other than the one where Cheever was eventually sentenced to death.
The U.S. Supreme Court disagreed, saying a defense expert's testimony on brain damage opened the door for prosecutors to use the mental health testimony from the second trial.
Cheever was convicted and sentenced to death in 2007 for killing Greenwood County Sheriff Matt Samuels as part of a meth lab raid in 2005.
Arguments were heard two months ago. There is currently no word on whether additional appeals will be filed.
