Jeremiah Barrett pleaded guilty Monday to one count of felony manslaughter in connection to the shooting death of Wesley David Smith at a marijuana garden near Mountain Ranch in October of 2015.
According to court documents, Barrett will be sentenced to six years in prison. He also admit to an additional firearm allegation with the plea.
Per the admission of guilt, Barrett was found not guilty of a felony murder in the second degree charge and two other felony manslaughter allegations.
Barrett has been in custody of the Calaveras County Jail in connection with the shooting deaths of Smith, Daniel Haney and Terry Glen Looney Jr. since the incident.
Barrett allegedly shot and killed Smith at a marijuana garden his brother, Leon Grammer, owned in the early morning hours on the day of the incident. Smith was shot initially with a 12-gauge shotgun and again seconds later by a derringer in the back of the head.
Barrett maintained since his arrest his actions were done in self defense. Smith was part of a group of three that were allegedly running at him, threatening his life and were high on meth when Barrett arrived to the property that day.
The defendant alleged he feared Smith was grabbing for a gun shortly after he was struck initially by the shotgun.
The plea comes two months after a jury acquitted Barrett of two felony murder charges in the shooting deaths of Haney and Looney at the garden.
A mistrial was eventually declared after the jury could not come to a consensus on the third felony murder charge, of Smith, and three other felony manslaughter allegations. It was an 11-1 split.
Barrett will be sentenced on May 24.
