Today, Judge Christopher Wilson sentenced 24-year-old Maxx Carson Robison to 23 years to life for the second-degree murder of Rhianna Skye McKenzie, who was 19 at the time of the murder. Mr. Robison pled guilty, and also admitted to using a firearm and to committing the murder from a moving vehicle. Mr. Robison also pled guilty to the attempted murder of Elisha Mansell, for which he will receive a concurrent 9-year sentence. 

This case occurred on June 30, 2016, when the defendant - who had been drinking - decided he also wanted drugs. This goal led him to the McCullens Motel, where he began banging on doors and accosting residents trying to find a supplier. Mr. Mansell confronted the defendant and told him to leave because no one at the motel sold drugs. During the argument, Mr. Mansell produced a small-caliber handgun and fired several warning shots intended to motivate Mr. Robison to leave. Mr. Robison left, but immediately returned with an AK-47-style semi-automatic rifle and fired multiple rounds into Mr. Mansell’s car, then occupied by Mr. Mansell and Ms. McKenzie. Ms. McKenzie died while Mr. Mansell narrowly escaped death: a bullet went through the top of the hat he was wearing.

Due to the conviction of murder, Mr. Robison will not receive time credit for good behavior or work while in prison. As part of the negotiated disposition, Mr. Robison waived more than three years of credits for time served in the Humboldt County jail from February 22, 2017, through March 11, 2020. The Eureka Police Department handled the investigation and Deputy District Attorney Roger Rees prosecuted the case with assistance from Deputy District Attorney Carolyn Schaffer, victim advocate Marybeth Bian, and District Attorney Investigator Marvin Kirkpatrick. Russell Clanton represented the defendant.  

Mr. Robison has been in custody since committing the crimes, and will be transferred to the Department of Corrections and Rehabilitation as soon as they resume accepting inmates. The defendant will become eligible for a parole hearing during his 23rd year of incarceration.
