On January 30, 2023, George Ramirez, aged 66, was found shot to death alongside his wife, Sonia Ramirez, 68, and their son, David Ramirez, 43, in their home on Ramona Place in Ontario, California. The San Bernardino County Sheriff's Department launched an investigation into the triple homicide, identifying the victims' grandson and nephew, 29-year-old Pete Anthony Renteria, as the primary suspect.
Despite extensive efforts, Renteria remained at large for several months.
The case took a significant turn on September 30, 2023, when Upland Police Department officers responded to a fatal shooting at Memorial Park in Upland, California. At the scene, they apprehended Renteria, who was found in possession of a handgun believed to have been used in the incident. The victim, a 34-year-old man, was pronounced dead at the scene.
Investigators revealed that Renteria had a prior altercation with the Memorial Park victim and had returned to the location to specifically target him. This arrest not only brought Renteria into custody for the recent shooting but also connected him to the unresolved triple homicide of his family members earlier in the year. He was subsequently booked into the San Bernardino County Jail, facing multiple charges, including murder.
The motive behind the killings of George, Sonia, and David Ramirez remains unclear. Family members described George and Sonia as devoted and compassionate individuals, and David as a supportive son and father. The arrest of Renteria has provided some relief to the grieving family, though many questions about the tragic events remain unanswered.
