Billings, MT - Zachary O'Neill was sentenced to life in prison Friday after pleading guilty in July to killing Miranda Fenner at a business in Laurel in 1998.

The Yellowstone County Sheriff's Office announced in July that O'Neill admission closed the 20-year-old cold case.

Miranda Fenner was murdered November 15, 1998, at the movie store in Laurel. 

Sheriff Mike Linder says O'Neill admitted two years ago to the crime while speaking to investigators in an unrelated case.

O'Neill is already serving time in Washington State on an unrelated crime.
