In May 2025, two-month-old infant Walter was rushed to a hospital in Arcadia, a prosperous, majority-Asian Los Angeles suburb nicknamed the “Chinese Beverly Hills.” The woman who identified herself as his mother initially told responding law enforcement that the infant had suffered a head injury after an accidental fall from a bed, but attending medical staff immediately flagged inconsistencies: Walter’s traumatic injuries aligned far more closely with blunt force impacts from a high-speed collision or violent shaking than a short fall.
Prompted by the medical team’s child abuse suspicion, local law enforcement executed a search warrant on the sprawling 10,000-square-foot, nine-bedroom Arcadia mansion where Walter resided, briefly detaining the two adults at the property: 66-year-old Guojun Xuan and 39-year-old Silvia Zhang. What investigators uncovered inside the surveillance-laden residence, Los Angeles County District Attorney Nathan Hochman later stated during an October press conference, could only be described as a “house of horrors.” Hidden across the property, 32 motion-activated cameras documented 14 surrogate-born children between six months and three years old, who prosecutors allege were subjected to routine physical beatings. Footage captured the toddlers spending hours confined to desks, with audio recordings of screaming coming from a single camera-free room where nannies were regularly seen carrying the young children. Authorities also identified the property as the unregistered headquarters of Mark Surrogacy, a surrogacy agency secretly operated by Xuan and Zhang to recruit gestational carriers.
The pair were formally arrested in October 2025 on charges of conspiracy to commit child abuse, pleading not guilty while being held in custody on individual $20 million bonds. If convicted, Xuan faces a maximum 17 years and four months of incarceration, while Zhang could receive up to 11 years and eight months. A third suspect, 61-year-old nanny Chunmei Li, has been charged with severe child abuse for allegedly inflicting Walter’s injuries and remains at large as a fugitive. The couple’s defense attorney Mitchell Krems has dismissed all allegations as a deliberate “mischaracterization” of available evidence, claiming Xuan is being targeted for exercising his constitutional right to build a large family.
The high-profile case has cast a harsh spotlight on the largely unregulated cross-border US surrogacy industry, a leading global destination for intended parents seeking assisted reproductive services that remain banned or heavily restricted in their home countries. A 2024 industry study found that nearly one-third of all international intended parents accessing US surrogacy services between 2014 and 2020 hailed from China, where commercial surrogacy is fully prohibited, making China the largest single source of foreign clients. Many of these clients are individuals locked out of domestic IVF and fertility support for single people and LGBTQ communities, or couples who missed their chance to conceive naturally after decades of the now-repealed One-Child Policy.
Court documents reveal that Xuan and Zhang deliberately concealed their ownership of Mark Surrogacy from dozens of gestational carriers, leading multiple surrogates to file civil lawsuits against the pair for fraud and intentional misrepresentation. Six women allege they were falsely told they were the only surrogate working for the couple, tricked into believing they were helping a small, loving family welcome one single cherished child. The pair also contracted with third-party California surrogacy agency Babytree Surrogacy, whose founder Patrick Yu told investigators he was unaware the couple had arranged for more than 20 surrogate children until news of Walter’s injury broke, immediately severing all ties with the pair.
Reproductive health legal experts confirm no existing US federal or California state laws cap the number of surrogacy arrangements a single intended parent can pursue, nor mandate full disclosure of prior surrogacy attempts to agencies or carriers, creating a largely unregulated grey area that wealthy clients often exploit to avoid public scrutiny. Prosecutors have confirmed Xuan and Zhang’s combined net worth exceeds $100 million, and Xuan holds three separate passports from China, the United States, and Mexico. A former high-ranking provincial legislator in China’s Xinjiang Autonomous Region who later led the US Xinjiang Chamber of Commerce, Xuan previously made a $4,900 campaign donation to disgraced former Arcadia mayor Eileen Wang, who resigned in May 2025 after pleading guilty to acting as an unregistered illegal agent of the Chinese government. In total, 26 children have been linked to the couple’s surrogacy network: 21 were placed under state protective custody during the 2025 investigation, with five more born after the probe launched. One infant born in early 2026 remains in the care of her Virginia-based surrogate mother Melissa Epps, who is fighting the couple’s legal attempt to seize custody of the child and claim $1 million in damages for alleged surrogacy contract breach.
