Nikki Dion Metcalf, aged 40, tragically lost her life on February 10, 2021, in a horrific incident that shook the community of Loleta, California. Metcalf was one of three victims in a triple homicide that occurred at a home on the Bear River Band of the Rohnerville Rancheria Reservation. The other victims were Margarett Lee Moon, also 40, and Moon's 16-year-old daughter, Shelly Autumn Mae Moon.
The suspect, Mauricio Eduardo Johnson, an 18-year-old man from Loleta, was known to the victims and was a guest in their home at the time of the shootings. Johnson had a relationship with Shelly, though the exact nature of their relationship was still under investigation at the time.
On the morning of the incident, a juvenile in the home called 911 to report the shooting. Deputies arrived to find two people dead and a third with serious injuries, who later died at a local hospital. Two children, aged 11 and 13, were also present in the home but were unharmed. The community was left heartbroken by the loss, particularly as both Shelly and Margarett Lee Moon were well-known and loved for their work at Loleta Elementary School, where they tutored students and worked in the afterschool program.
The investigation into the motive behind the killings was ongoing, but it was clear that the suspect had been given permission to be in the house by at least one of the residents. The Humboldt County Sheriff's Office, along with a major crimes task force, worked diligently to piece together the events leading up to the tragedy. The impact of the murders was profound, with the Bear River and Loleta communities mourning the loss of three beloved individuals.
In the aftermath, Mauricio Johnson was arrested in Utah a day after the shootings while traveling with his mother and her friend. He was reportedly heading to a family member's residence in Indiana. Johnson later pleaded guilty to three counts of first-degree murder and admitted to three special allegations of using a firearm in the killings. He was sentenced to 150 years to life in prison, with a parole hearing set for 25 years later, as per California law for young offenders. The plea deal was accepted by the prosecution after consultations with the victims' families and community members, who had differing views on whether to accept the plea or proceed to trial.
