Man Pleads Guilty in Double Homicide of His Parents

Santa Rosa, CA  –  January 30, 2017  –  Defendant Nathan Alexander Wilson, 35 years-old of Sebastopol, pled guilty today to two separate counts of murder stemming from an incident on November 23, 2015, in which Wilson killed both of his parents inside their Sebastopol home. 

District Attorney Ravitch stated, “This was obviously a very tragic event and our thoughts are with the family members of these two victims.  We hope the resolution of this case can bring some sense of closure to them.”

The charges resulted from an incident in which Wilson inflicted numerous stabbing and slashing wounds on both of his parents, David Joel Wilson and Adrianne Louise Chapin.  At the time of the murders, Wilson had been living in an out-building on his parents’ property in Sebastopol. The morning after the killings Wilson was seen by his uncle at the family’s home, but he left before law enforcement arrived.  Wilson was located later that day in Mendocino County.  Wilson’s history indicated unstable mental health.     

Wilson was charged with two counts of murder, and allegations as to each count that he personally used a deadly weapon, and personally inflicted great bodily injury upon each of the victims. It was also alleged Wilson committed multiple murders, a special circumstance under California’s homicide laws.  Prior to trial, the District Attorney’s Office and Wilson reached a plea agreement in which Wilson plead guilty to both murders, admitted the allegations that he personally used a deadly weapon, and personally inflicted great bodily injury upon the victims during the commission of the crimes.  However, Wilson did not have to admit the special circumstance that would have called for a sentence of life without parole.   Instead, the two murder convictions will result in a sentence of forty years-to-life in prison. Sentencing is set for March 3, 2017.

This case was prosecuted by Deputy District Attorneys Jason Riehl and Andrew Lukas. Detective Joseph Horsman from the Sonoma County Sherriff’s Department headed the investigation.
