Topeka ? The Kansas Supreme Court on Friday upheld a first-degree murder conviction in a 2007 killing and dismemberment in Manhattan.

The court on Friday rejected arguments from attorneys for Kevin Hernandez, who is serving a life sentence with no chance of parole for 50 years in the death of Adam Hooks.

The Topeka Capital-Journal reports that Hernandez’s attorney claimed the prosecutor made a prejudicial error in closing arguments, and that the “hard 50” sentence was unconstitutional. And the attorney said a Riley County District Court judge should have provided jury instructions on voluntary intoxication and second-degree murder.

Hooks was beaten to death in his Manhattan home. Prosecutors say Hernandez dismembered Hooks’ body but was arrested before he got rid of the evidence.
