Geneva County District Attorney Kirke Adams says Patrick Cochran
entered the plea Friday in the December 1994 death of 68-year-old
Authorities say Cochran was 19 when he brutally beat McKenzie with a fire extinguisher and stabbed him multiple times at his home in Geneva.
Cochran could have faced the death penalty had he gone to trial.
Cochran was charged with the killing in 2009 while serving a 10-year sentence in a state prison in Graceville, Fla., on charges of lewd and lascivious battery against a child.
