Judge Timothy Canning handed down the sentence that was part of a plea deal for Mauricio Johnson, who was a guest in the home when he killed Nikki Dion Metcalf and Margarett Lee Moon, both 40, and Moon's 16-year-old daughter, Shelly Autumn Mae Moon, on Feb. One year after a newly engaged couple and a 16-year-old girl were shot to death at a home on the Bear River Band of the Rohnerville Rancheria Reservation, the now 19 year old who pleaded guilty to their murders was sentenced today to 150 years to life in prison. Nikki Dion Metcalf, Margarett Lee Moon and Shelly Autumn Mae Moon (left to right) were fatally shot the morning of Feb 10 in their home on the Bear River Band of the Rohnerville Rancheria Reservation, leaving a community in mourning.
