A disturbing discovery in a remote part of Riverside County has led to a murder arrest after investigators identified a woman whose remains were found near Anza earlier this month.
Authorities have identified the victim as 43-year-old Jessica Rodriguez of Hemet. Joseph Rainey, 40, also a Hemet resident, was arrested in connection with her death and booked on suspicion of murder.
The investigation began on October 23, 2026, when deputies responded to the area of Bautista Canyon Road and Willis Road in Anza at approximately 2:29 p.m. after reports of human remains.
The location is in an unincorporated part of Riverside County, away from the more populated communities in the region.
Deputies discovered the remains of an adult woman, prompting the Riverside County Sheriff’s Central Homicide Unit to take over the case.
What initially appeared to be a suspicious death investigation soon developed into a homicide investigation after an autopsy provided investigators with evidence that the woman had been killed.
Investigators identify the victim and suspect
Identifying the woman was an important step in moving the investigation forward.
Authorities later confirmed that the victim was Jessica Rodriguez, a 43-year-old woman from Hemet. Investigators then worked to establish the circumstances surrounding her death and identify a possible suspect.
During their investigation, detectives identified Joseph Rainey, 40, also from Hemet, as the suspect.
Officials have not publicly explained what may have led to the killing or whether Rodriguez and Rainey knew each other.
The lack of publicly released information leaves several questions unanswered as detectives continue examining the circumstances of the case.
Search of Hemet home leads to evidence seizure
On October 29, investigators located Rainey in the 1400 block of State Street and took him into custody without incident.
Detectives also carried out a search warrant at his residence. During the search, they recovered multiple items believed to be connected to the investigation.
Authorities have not disclosed what those items were or explained how they may relate to Rodriguez’s death.
Following his arrest, Rainey was booked into the Cois Byrd Detention Center on suspicion of murder.
The investigation remains active, and officials have not released additional details about the evidence or a possible motive.
Earlier investigation sought information about a missing woman
Before Rodriguez’s identity was publicly confirmed, investigators had asked residents in the Hemet and Anza areas to help identify the woman.
Authorities were particularly interested in information about adult women who had gone missing or had not been heard from since October 9.
That earlier public appeal was an important part of the investigation as detectives worked to establish the victim’s identity.
The subsequent identification of Rodriguez and arrest of Rainey marked significant developments in the case.
However, investigators have not provided a complete account of what happened before the woman’s remains were discovered.
What happens next?
With Rainey in custody, the case moves into the next stage of the criminal justice process.
Investigators are continuing to review evidence collected during the investigation, including items recovered from the residence. Additional information may become available as the case progresses through the courts.
An arrest does not establish guilt, and the allegations against Rainey must be addressed through the legal process.
For now, authorities have not announced a motive, disclosed the relationship between the suspect and victim, or released further details about the circumstances of Rodriguez’s death.
Police ask the public to come forward
The Riverside County Sheriff’s Office is asking anyone with information that could help investigators to contact Central Homicide Unit Investigator Daniel DiMaggio.
Anyone with relevant information can call 951-955-2777.
Even details that may initially seem minor could help detectives establish a clearer timeline or provide additional information about the events leading up to Rodriguez’s death.
For the community, the arrest is a significant development, but the investigation is far from over. Authorities say the case remains active as they continue working to establish exactly what happened.
