This was an intriguing case that received a surprisingly cursory and unanimous resolution.
Cheever was chronic methamphetamine user. One day, back in 2005, he cooked and smoked meth. Coincidentally, the police showed up to handle an unrelated warrant. He shot and killed the sheriff of Greenwood County, Kansas, then fired at other officers until he was eventually detained.
He was first charged with a capital offense in state court, but the charges were dropped when Kansas declared its death penalty to be unconstitutional. Federal charges were brought, but the trial was halted when defense counsel was unable to continue. Meanwhile, the Supreme Court reinstated Kansas's death penalty. State charges were brought once again.
