Discovered in 2015

Anita’s remains were discovered partially submerged in 2015 due to the historically low, drought-era level of the Stanislaus River beneath the Parrotts Ferry Bridge. The original investigation revealed that the remains belonged to an unidentified female who was likely the victim of homicide.

Calaveras Cold Case Task Force Announces Identification of Parrotts Ferry Jane Doe
Calaveras County, CA

The Calaveras Cold Case Task Force is announcing that, through continued efforts and in partnership with forensic investigative specialists, the identity of the woman previously known as “Parrotts Ferry Jane Doe” has been confirmed.

Anita Kathleen Ranker, born February 18, 1969, in Santa Clara County, has been identified as the woman whose remains were found on October 9th, 2015, beneath the Parrotts Ferry Bridge.

After more than a decade of remaining nameless, this identification represents a significant breakthrough in a case that had gone cold. Through the continued efforts of the Calaveras Cold Case Task Force and the use of modern forensic technology, investigators have been able to provide long-awaited answers regarding the identity of a woman who remained unknown for far too long.

Anita’s remains were discovered partially submerged in 2015 due to the historically low, drought-era level of the Stanislaus River beneath the Parrotts Ferry Bridge. The original investigation revealed that the remains belonged to an unidentified female who was likely the victim of homicide.

Despite extensive investigative efforts, the woman’s identity remained unknown following her discovery, and the case eventually went cold. In 2021, following the creation of the Calaveras Cold Case Task Force, the case was reopened with hopes of using advancements in forensic science to provide answers.

Over the ensuing years, the remains were sent to numerous laboratories, each using cutting-edge technology to attempt to extract DNA suitable for Forensic Genetic Genealogy. The extraction of DNA was complicated by the degradation of the remains, which occurred from being underwater for many years. Resolve Forensics of Utah provided over three years of laboratory services while assigned to this case, making significant progress on extracting DNA suitable for Forensic Genetic Genealogy from the remains.

In June 2026, Astrea Forensics in California successfully extracted usable DNA. Following the successful extraction of DNA, Forensic Investigative Genetic Genealogy work conducted by Identifinders International led to the discovery of Anita’s relatives, who voluntarily provided a DNA reference sample.

The DNA reference samples have confirmed the identity of Anita Ranker through a two-pronged approach: private laboratory work and the California Department of Justice.

The investigation into the circumstances surrounding Anita’s death remains active. Task Force members will continue working to gather additional information, identify those responsible, and bring accountability for the crime committed against her.

Investigators believe Ranker disappeared prior to the year 2000. She was never reported missing, and a person of interest has been identified. Anita is believed to have been living in or around Murphys, CA, at the time of her death.

The Calaveras County Cold Case Task Force would like to thank the donors, forensic specialists, partner agencies, investigators, and community members who have supported this investigation over the years. Advances in technology, combined with the dedication of those who refuse to give up on unresolved cases, continue to provide new opportunities to bring answers to victims and their families.

“Every unidentified person represents a family, friends, and a life story that deserves to be known,” said Sheriff Rachelle Whiting. “The identification of Parrotts Ferry Jane Doe is a testament to the dedication and perseverance of the Cold Case Task Force and the forensic partners who continued working toward the goal of restoring Anita Ranker’s name.”

The Sheriff’s Office encourages anyone with information related to this investigation to contact the Calaveras County Sheriff’s Office at (209) 754-6500 or provide information through the department’s anonymous tip line at (209) 754-6030.

The laboratory and forensic costs associated with this investigation have exceeded $50,000. This work was made possible entirely through tax-deductible donations to the Calaveras Cold Case Task Force, allowing us to continue searching for the answers that families deserve.

 

The Mission

The Calaveras Cold Case Task Force was formed to assist Calaveras Law Enforcement Agencies in solving cold cases within Calaveras County. This includes funding costly forensic DNA analysis of unidentified human remains, finding missing persons, and solving homicides and other longstanding crimes.

The need

Many cases in Calaveras County have grown “cold” over the years due to a lack of investigative leads, no means of identifying human remains, and a lack of funding for private laboratory services that state government laboratories don’t provide.

Top Cold Cases

Please note that the team is investigating many cases that are not being shared at this time. These are just a few.

 

Identifying the Victims of Serial Killers

The Wilseyville Serial Killings:

The Wilseyville Serial Killings were committed in the mid-1980’s by a duo of killers.  Of the two killers, Charles Ng was convicted of 11 counts of murder, and Leonard Lake committed suicide upon his capture.  The Calaveras Cold Case Task Force will follow the “No Notoriety” model and minimize the suspects’ names in press releases or case summaries from this point forward.  

The Wilseyville Serial Killings left numerous victims, including whole families, whose remains were never identified. Over 1,000 pieces of human bone fragments and teeth were discovered at the scene of these horrific crimes. Experts have classified some of these bones as belonging to infants and toddlers. It is believed there may be victims who have remained unknown all these years, and the team intends to identify these nameless victims, ensure that they are remembered, and bring their stories to light.

Originally placed in a crypt in the People’s Cemetery in San Andreas, CA, the CCTF obtained a court order to exhume the remains and begin the identification process. The goal is to return the victims to their loved ones so they can be laid to rest. The team is actively working to identify each piece of the unidentified bones and teeth with the help of cutting-edge DNA and forensic genetic genealogy.

For information on previously unknown victim Reginald Frisby, please visit his page for information on his identification and remains being sent home to be laid to rest.

Please see the Brenda O’Connor page for information on her remains being sent home to be laid to rest.

 

Identifying the ParrotTs Ferry Jane Doe

Jane Doe was discovered in the waters of the Stanislaus River below the Parrotts Ferry Bridge in 2015. Her remains consisted of a torso and thighs. A chain was wrapped around her waist, and a concrete block was found nearby. Her remains have not been identified, but due to progress in DNA technology and techniques, the team is close to identifying this lost and forgotten woman who became the victim of a violent murderer.

Update:  The Calaveras Cold Case Task Force is committed to identifying Jane and restoring her proper name.   To date, nearly $30,000 of supporter funds have been spent on this case, and as of late 2024, a DNA profile has been successfully extracted by Astrea Forensics.

This DNA profile is assigned to our partners at Identifinders International LLC and is undergoing a Forensic Genetic Genealogy Investigation. Check back for updates on this case.  

 

Discovering the identity of a Killer: Roy Dixon Homicide

In 1997, the body of Roy Dixon was discovered alongside Winton Road a few miles outside West Point, CA, near his burned Jeep Cherokee. Investigators determined that the fire had been ignited deliberately and that Dixon had been murdered. Although several leads were developed during the investigation, evidence and leads were not sufficient to arrest and charge the perpetrator(s) of the murder. Dixon’s homicide has remained an open case for nearly three decades, but the Cold Case Task Force is reexamining all the evidence, analyzing DNA, and utilizing modern forensic science to hopefully solve the case and bring Dixon’s killer to justice.

 

Hector Girol Homicide

Hector Girol was shot while taking a shower at his home in Copperopolis, CA in 2000. While several leads were established at the time, there was insufficient evidence to bring his killer to justice. However, the team is working with scientists to create new leads with the intention of solving this longstanding mystery and giving Hector the justice he deserves.
