STOCKTON — Stockton police announced Wednesday that two suspicious death investigations are now considered homicides, two others are not considered homicides and one case that was initially ruled a homicide has now been reclassified as a drug overdose.   

Officer Joe Silva, a spokesman for the Stockton Police Department, provided updates on the cases after detectives received results of autopsies and toxicology tests from the San Joaquin County Coroner’s Office. Autopsies were performed Wednesday on three women who were found dead in recent days in unrelated incidents.

Silva said the death of a woman who was found deceased with signs of trauma at 2:33 p.m. Monday inside her home in the 200 block of Pearl Avenue has been ruled a homicide. Police responded to the home to conduct a welfare check after the woman did not respond to a school bus to pick up her special-needs child, authorities said.

Silva said an autopsy showed that the woman was the victim of a physical assault. The San Joaquin County Coroner’s Office has not released her name. The woman’s child has been placed in the care of family members, Silva said.

“During the autopsy, it was determined that she had been assaulted, and this case is now considered a homicide,” Silva said.

Silva said the deaths of two other women who were found dead Saturday were not homicides. The Coroner’s Office on Wednesday identified those women as Nancy Moreno, 33, and Orn Dok, 50, both of Stockton.

Moreno’s body was found at 5:48 p.m. Saturday inside her home on Gateway Court, police said. Dok was found dead inside her locked vehicle at 10:04 p.m. Saturday in the Oak Park area. Police did not reveal the cause of death in either case.

“Based on the autopsies, it was determined that there was no foul play involved in those two cases,” Silva said.

Silva said the death of Michael James Feagan, 63, has been ruled a homicide. A friend found Feagan dead at 9:55 p.m. June 3 inside his home in the 500 block of East Essex Street, just north of North Sutter Street. Police initially classified the case as a suspicious death and said they would await autopsy and toxicology results before determining if it was a homicide.

The death of George Casillas, a 57-year-old Stockton man, was initially ruled a homicide, but it has now been reclassified as a drug overdose, Silva said. Casillas’ body was found after firefighters responded to a report of a fire at 6:21 a.m. March 26 in the 2100 block of East Taylor Street near Stribley Park. The fire consumed a trailer home and a small shed behind the trailer in which Casillas was living.

Police arrested Sarah Zavala, 26, on suspicion of murder and arson, alleging that Zavala intentionally started the fire. A neighbor told The Record that Zavala threatened to “burn the place down” after an eviction notice was posted on her trailer a day before the blaze.

Silva said autopsy and toxicology results revealed that Casillas had died of a drug overdose before Zavala set the fire. Zavala is still being held at the San Joaquin County Jail on $300,000 bail. She is now facing two felony charges of arson and arson of an inhabited structure.

Police have not made any arrests if the deaths of Feagan and the woman whose body was found Monday on Pearl Avenue.
