Ronald Patrick Drinkard, 50, was shot to death on March 22, 2015, at his home on Coyote Holler Road in Potrero, California, a rural area about 45 miles southeast of downtown San Diego. Deputies responding to a call found Drinkard’s body on the front porch of neighbor Michael Walliser’s home. The San Diego County Medical Examiner ruled the cause of death multiple gunshot wounds and classified it a homicide.

Walliser, 68 at the time, called the San Diego County Sheriff’s Department the night of the shooting and was arrested and booked into San Diego Central Jail, then released that same night when charges were not immediately filed. Investigators described a long-standing dispute between the neighbors as the apparent origin of the shooting; the Sheriff’s Department asked anyone with information to come forward.

Does anyone in the Potrero or Escondido area have information about the relationship between these neighbors or the events leading up to March 22, 2015?
