California Man Faces Murder Charges in Six-Year-Old Disappearance of Pregnant Teen
A California man has been formally charged with the murder of his pregnant high school girlfriend, bringing a dramatic development in a case that had remained unsolved for six years. Joshua Martinez, now 28 years old, was arraigned in San Joaquin County Superior Court on Monday following his arrest last Thursday.
Whirlwind Relationship and Tragic Disappearance
Prosecutors described the relationship between Martinez and 16-year-old Victoria Marquina as a 'whirlwind, very fast relationship' that began approximately one month before her disappearance in October 2019. During that brief period, Marquina became pregnant. Martinez, who was 21 at the time, is believed to have been the last person to see the teenager alive before she vanished without a trace.
Victoria Marquina was last seen alive on October 9, 2019 near her workplace in Amador County, California, approximately 130 miles northwest of San Francisco. Her mother reported her missing the following day in Sutter Creek. Three days after her disappearance, Marquina's car was discovered abandoned near Escalon, about 50 miles from her home. She has not been seen or heard from since that time.
Multiple Charges Filed Against Suspect
Martinez now faces multiple serious charges including murder, unlawful intercourse with a minor more than three years younger, oral sex with a person under 18, and sexual penetration by a foreign object with a minor. If convicted on the murder charge, he could potentially face life in prison.
San Joaquin County District Attorney Ron Freitas delivered a powerful message during Monday's press conference, stating: 'To the criminals who believe that with the passage of time we will forget your heinous acts: you are wrong.' He emphasized that technological advances over the past year had enabled prosecutors to move forward with charges despite the six-year gap since Marquina's disappearance.
Technological Breakthroughs Revive Cold Case
Authorities revealed that new technology and information helped crack the case, which had previously fallen apart in 2020. While specific details about the technological breakthroughs were not disclosed, District Attorney Freitas credited 'dogged tirelessness' in the investigation and meticulous attention to detail for the breakthrough.
Martinez was arrested in Livermore last week by U.S. Marshals after a grand jury issued a warrant earlier this month. He is currently being held without bail in the San Joaquin County Jail while awaiting trial and is scheduled to return to court on April 6 for further arraignment. It remains unclear who, if anyone, is representing him legally.
Previous Legal Proceedings and International Flight
This is not Martinez's first encounter with the legal system regarding this case. He was previously held behind bars for approximately six months in 2020, but prosecutors were unable to charge him with Marquina's murder at that time because her body had not been found. Investigators revealed that Martinez fled to Mexico shortly after the teenager vanished.
He was arrested by Amador County investigators in June 2020 on charges related to sex with a minor. During previous proceedings, Martinez claimed he crossed the border because he was receiving death threats regarding Marquina's disappearance. He admitted to dropping her off in Sutter Creek but maintained that was the last time he saw her.
Contradicting prosecution claims, Martinez denied having been in a relationship with Marquina at the time of her disappearance. Instead, he asserted that the pair had met through a dating site and that she had lied about her age.
Ongoing Search for Remains and Family's Anguish
Tragically, Marquina's body has still not been found, with investigators continuing to search for the remains of both her and her unborn child. District Attorney Freitas expressed the investigation's primary goal: 'We want to bring closure to Victoria's mother and allow her to bury her child and her grandchild.'
Amador County District Attorney Todd Riebe, whose office supported the investigation and has jurisdiction in Sutter Creek where Marquina was reported missing, stated: 'Today marks the beginning of Victoria Marquina's journey for justice.' He added that this development would not have been possible without her mother's 'unyielding love.'
Mother's Heartbreaking Testimony
Marquina's mother, Blance Valencia, shared poignant memories of her daughter during a recent interview. 'I think that by now she would be graduated, received, and would be a fulfilled woman,' Valencia told CBS Sacramento. 'Unfortunately, someone cut us off.' Despite the years that have passed, she maintains hope: 'But I still have faith. I still have hope that she will return home.'
Valencia described her teenage daughter as having 'many dreams' that were tragically cut short. The case continues to draw attention as legal proceedings move forward, with authorities expressing confidence that justice will ultimately be served for Victoria Marquina and her unborn child.
