An apparent dispute between a mother and daughter ended early Friday in the death of a 60-year-old Paso Robles woman, the tragic culmination of what neighbors call a disturbing chain of events.

Paso Robles police officers went to the 900 block of Olive Street on the city’s west side at 6:15 a.m. after a neighbor called 911.

Police found a woman dead inside a one-bedroom granny unit and another woman sitting outside. The victim’s name, injuries and the manner of her death were not disclosed Friday.

Police arrested 36-year-old Sunni Daun Jackson, whom they said is the victim’s daughter, on suspicion of murder. She was taken into custody and then went to County Jail; she is expected to be arraigned next week.

Police said the victim’s name was being withheld pending positive identification by the San Luis Obispo County Coroner’s Office.

Jean Fisher, a neighbor living across the street from where the homicide occurred, said her boyfriend, Jesse Cardoza, went outside Friday morning and heard “blood-curdling screams and breaking glass.”

“He walked to the corner to see what was happening, and the screams got worse,” Fisher said. “He did not know what to do. So he called the police.

“He’s horrified that he pretty much witnessed a murder,” she said. “He told me, ‘Babe, I was the last one to hear her last screams.’ He’s just real upset about it.”

Fisher said her boyfriend did not hear any gunshots. An autopsy will be performed Monday or Tuesday, authorities said.

When the victim’s apparent family members started showing up in the neighborhood Friday morning, neighbors said they got a better idea of who had died.

Among the visitors was a woman neighbors thought was another of the victim’s daughters. She appeared visibly upset when she saw yellow crime tape stretched across the driveway, they said.

“She started screaming that she had to go to the hospital because she was going to have a breakdown,” Fisher said. “She almost threw up multiple times, right there on the corner.”

A younger woman also visited the crime scene, and the same two neighbors heard her pleading with police to tell her that it wasn’t her grandmother who was dead inside.

Investigators remained at the home Friday after receiving a warrant to search the interior for evidence.

The California Department of Justice was also at the scene with a mobile crime lab from Goleta to assist with the Paso Robles Police Department’s investigation.
