Man Sentenced in Killing of Potrero Neighbor

Michael Walliser, 68, shot and killed his neighbor, Ronald Drinkard, 50, on March 22, 2015, at his home in Potrero

A man who admitted to killing his neighbor - after he had been jailed more than a year ago for the crime, but then released - was sentenced to more than three years in prison.

Michael Walliser, 68, is accused of shooting and killing his neighbor, Ronald Drinkard, 50, on March 22, 2015, at his home in the 23300 block of Coyote Holler Road in Potrero, a rural community about 45 miles southeast of downtown San Diego.

The San Diego County Medical Examiner’s (ME) office conducted an autopsy on Drinkard and determined he was a victim of homicide and had died from multiple gunshot wounds.

On Feb. 10, 2016, SDSO homicide detectives issued a warrant for Walliser’s arrest on one count of murder. The next day, Walliser was taken into custody at his home on Bartley Place in Escondido.

Walliser later pleaded guilty to voluntary manslaughter in the shooting death of his neighbor. 

According to a plea bargain between the parties, Walliser was sentenced to three years and eight months in state prison.
