Gary Gamble entered the guilty plea before Warren Circuit Judge John Grise Thursday morning. Gamble and Charles Morse were charged with killing 21-year-old James Corey Webster of Owensboro. The former Western Kentucky University student was found shot to death outside his home in Willow Creek Apartments in November, 2003. Morse has already confessed to the crime and will testify at next week's jury trial to set Gamble's sentence. Gamble could get anywhere from 20 years to life in prison.
