Jurors convicted two Sonoma County men of second-degree murder Tuesday in a Healdsburg-area pot garden slaying that stoked fear about violence at marijuana farms.
Sidonio Cruz-Santos, 36, of Santa Rosa and Agustin Zepeda-Onofre, 25, of Windsor, were convicted of killing Gabino Lopez-Santiago, 46, of Healdsburg.
The two men, who witnesses said were frequently armed, were growing marijuana on a wooded hillside on Chemise Road near Dry Creek Valley. Lopez-Santiago was the brother-in-law of a man they hired to trim and process their pot.
The night of the killing, they were all partying at the garden when an argument broke out and Lopez-Santiago and his brother-in-law were ordered to leave at gunpoint. Lopez-Santiago was shot by one of the defendants as he waited for his brother-in-law to get their truck.
It was unclear who pulled the trigger but both defendants were convicted under a "vicarious liability" theory, which held each man legally responsible for the actions of the other. Jurors rejected first-degree murder, which required a finding of premeditation.
"It was a just decision," prosecutor Anne Masterson said. "I feel confident in the verdict."
It came after about five days of deliberation. The trial spanned three weeks.
Each man was also convicted of three counts of assault with a firearm and felony cultivation. Cruz-Santos was found guilty of persuading a witness by force or threat.
They face life prison terms when they are sentenced.
They are the latest to be convicted in a series of pot-related homicides to strike Sonoma County in the past few years. In December, two men were convicted of murder in an October 2011 pot rip-off outside a southwest Santa Rosa meat market. Three men await trial in a February triple-slaying near Forestville that police say is tied to a pot deal.
