The Kansas Supreme Court has affirmed the convictions for a man serving a life sentence for killing the owner of a Wichita car dealership during a botched robbery.

Kedrin Littlejohn, 20, was found of first-degree murder, aggravated kidnapping and other charges in the death of James Collins in 2010.

Prosecutors say Collins was kidnapped from his business, Marquee Motors, on May 12, 2008. He briefly escaped but was shot and then run over.

A co-defendant, Shannon Bogguess was found guilty of first-degree murder and other charges in September 2009. He was also sentenced to life in prison.

The justices rejected Littlejohn's claims including the jury instructions were defective and the state presented insufficient evidence of his guilt.
