A 55-year-old La Mesa man was sentenced to just over 10 years in federal prison Wednesday for kidnapping his estranged wife from her apartment, beating her, and driving her toward the Mexican desert before a desperate signal at a border checkpoint helped save her life. Chad Oso showed up unannounced at the victim's La Mesa home in 2024, according to prosecutors, setting off a chain of events that turned a domestic dispute into an international federal case.
According to the Department of Justice, Oso beat and chased the victim when she tried to alert a neighbor, then dragged her downstairs and forced her into his vehicle before driving off. He left her two young children alone inside the apartment, prosecutors said. Prosecutors argued that the victim suffered injuries to various parts of her body during the assault. As Times of San Diego reports, court documents show Oso later argued the victim willingly got into his vehicle and denied assaulting her.
A Desperate Escape Attempt Through La Mesa Streets
As Oso drove around La Mesa refusing to let her go, the victim tried to escape and passersby saw her screaming for help, according to the Department of Justice. Passersby called 911, per the U.S. Attorney's Office as reported by Times of San Diego. Oso then continued into Mexico, where prosecutors said he intended to leave the victim in the desert.
Court documents show Oso later argued he did not drive into Mexico intentionally, per Times of San Diego. The crossing took the case across an international border.
A Signal at the Checkpoint Changes Everything
Rather than reaching the desert, the victim stuck her hand out of the vehicle window at a Mexican checkpoint, gaining the attention of Mexican Customs officials, according to the Department of Justice. Those officials turned the car back toward the U.S. border, where Customs and Border Protection officers rescued her and arrested Oso. The account describes CBP officers responding at the border.
A San Diego federal jury convicted Oso earlier in 2026. He was sentenced Wednesday to just over 10 years in federal prison by the U.S. District Court for the Southern District of California, the Department of Justice said. The account does not provide details about parole eligibility or the portion of the sentence Oso will serve.
Why a Local Dispute Became a Federal Case
Under the Federal Kidnapping Act, unlawfully seizing and transporting a person across international boundaries is a federal crime punishable by up to life in prison, according to Eisner Gorin LLP. That statute is part of the legal basis for Oso's federal case.
