Purkey, you might remember, kidnapped and killed a local teen named Jennifer Long back in 1998. Purkey really would like to get that death sentence kicked, but a federal judge has rejected his request for a new hearing. Besides arguing that his counsel was ineffective, and that the prosecutors misbehaved, Purkey argued that he shouldn't get the death penalty because he didn't actually take the girl across state lines. (Which landed him in federal court in the first place, which led to him getting the death penalty.)
UPDATED: Here's a ruling on an earlier appeal from Purkey, who reportedly confessed to 16-year-old Long's rape and murder because he wanted to do life in a federal prison, instead of getting death or ending up in a state facility. Purkey was already a suspect in the murder of an elderly woman, Mary Ruth Bales, by that point. From the court document ...
During the guilt phase of his federal trial, Mr. Purkey affirmed his statements about the killing and dismemberment of Ms. Long, but he disavowed his previous statements that he forced Ms. Long to travel with him from Missouri to his home in Kansas.
Instead, he stated that Ms. Long, who he said he thought was a prostitute, voluntarily entered his truck and accompanied him to his home. He indicated that he fabricated the kidnapping aspect of the confession to ensure that his actions would be considered, and therefore prosecuted as, a federal crime. After deliberating briefly, the jury returned a verdict of guilty.
