Sutter Creek, California – A chilling cold case from 2019 saw renewed momentum this week as authorities indicted a longtime person of interest in the presumed killing of 16-year-old Victoria Amairani Marquina.[1] The high school student from Amador County vanished without a trace, leaving her family in agony for over six years. Prosecutors in neighboring San Joaquin County secured the charges after fresh investigative efforts, marking a potential turning point in the search for answers.[2]
The Night She Vanished
Victoria Marquina planned an exciting evening on October 5, 2019. The teenager attended a concert in Sacramento and intended to return home to Sutter Creek that night.[3] Her mother last saw her the following day, October 6. Classmates reported spotting her on October 8, and her cellphone pinged for the final time on October 9.[4]
Eight days later, on October 13, authorities located her black Honda Accord abandoned in Escalon, a town in San Joaquin County about an hour south of Sutter Creek.[3][1] Her cellphone turned up nearby as well. No sign of Victoria emerged, and she has not been seen since. At the time, the 5-foot-1-inch Hispanic teen with brown hair and brown eyes weighed around 110 pounds.[4]
Spotlight on Joshua Anthony Martinez
Investigators quickly zeroed in on Joshua Anthony Martinez, then 21 years old. The two had connected online and entered an unlawful dating relationship, given Victoria’s age.[1] An eyewitness described seeing a Hispanic couple matching their appearances near Escalon between October 10 and 13.[3] Martinez claimed he last saw Victoria on October 6, when he dropped her off in Sutter Creek.
Shortly after her disappearance, Martinez fled to Mexico. U.S. authorities extradited him back in June 2020. He faced felony sex-related charges, including statutory rape, with Victoria as the victim in those counts. He remained in custody for six months before release.[3]
Twists and Turns in the Investigation
The case hit roadblocks early. In December 2020, Amador County Sheriff’s Office arrested Martinez again on a Ramey warrant for one count of felony murder. However, lack of concrete evidence led to his release soon after. The Amador County District Attorney issued a statement emphasizing their commitment while clarifying jurisdictional limits.[5]

Years passed with the case growing colder. Victoria’s family persisted in their pleas for justice, even as frustration mounted. In 2025, the San Joaquin County Sheriff’s Office launched a dedicated cold case task force, targeting unresolved mysteries like this one.[1]
- October 2019: Victoria disappears; car found in Escalon.
- June 2020: Martinez extradited from Mexico on sex charges.
- December 2020: Brief murder arrest, then released.
- 2025: New cold case unit forms.
- March 2026: Rearrest and indictment.
Indictment Delivers Long-Awaited Charges
On March 16, 2026, a San Joaquin County grand jury returned a true bill of indictment against Martinez, now 28.[1] He faces murder along with multiple child sex crimes. U.S. Marshals took him into custody, and he appeared in court the next day. Judges denied bail, keeping him at San Joaquin County Jail.[6]
Amador County District Attorney’s Office greenlit the prosecution under multi-county jurisdiction rules. The case shifted to San Joaquin due to evidence locations. Investigators cited circumstantial evidence pointing to Martinez as the killer, though Victoria’s body remains undiscovered.[1] Reports indicate she was pregnant at the time of her vanishing.[7]
A Glimmer of Closure
San Joaquin County District Attorney Ron Freitas spoke outside the courthouse after the hearing. “I met Victoria’s mom shortly after taking office and she told me her heartbreak and not knowing where her daughter was and not having the person that killed her being held accountable,” he said. “And it’s weighed heavily on me and it’s one of the things that I’ve thought about almost every single day since taking office.”[1]
The indictment offers hope amid prolonged grief. Families like the Marquinas have endured years without resolution, their pleas echoing through media and social campaigns. This development underscores persistent law enforcement efforts in cold cases.
Key Takeaways:
- Victoria Marquina vanished in October 2019; her car and phone were recovered soon after.
- Joshua Martinez faces murder and sex crime charges after prior releases.
- No body found, but grand jury indicted based on evidence.
