Guojun Xuan and Silvia Zhang were arrested Tuesday morning at their Arcadia mansion in a multi-agency raid.
Officers descended on the couple’s castle-like California home early Tuesday and detained both Xuan and Zhang on multiple charges, according to the source article. The pair stand accused of exploiting the state’s surrogacy laws to operate their own agency, Mark Surrogacy.
Local law enforcement and the FBI were observed combing through the residence following the early morning operation. The scale of the alleged scheme is striking: authorities say the couple “farmed” 21 children through their purported agency.
Xuan’s legal representation has mounted an aggressive defense. His attorney, Mitchell Krems, pointed the finger elsewhere entirely. “My client is innocent. It is the nanny’s wrongdoing who went on the run,” Krems said. “He is being targeted for exercising his constitutional right to have a large family.”
The attorney’s statement frames the prosecution as an attack on reproductive freedom rather than criminal enterprise. Krems did not elaborate on the nanny’s alleged role or current whereabouts.
The case touches on California’s notably permissive surrogacy framework, which has made the state a national hub for assisted reproduction arrangements. The alleged exploitation of these statutes for a private, unlicensed operation raises questions about regulatory gaps in the industry.
The 21 children reportedly connected to the couple represent an extraordinary number for any family unit, regardless of biological or gestational origin. How the children were housed, cared for, and whether any were placed with other families through the purported agency remain unclear from available details.
The FBI’s involvement suggests federal authorities are examining potential crimes beyond state jurisdiction. The nature of the multiple charges has not been fully specified in initial reporting.
Arcadia, an affluent Los Angeles County community, has seen its share of high-profile criminal cases, though few involving allegations of organized child farming through surrogacy exploitation. The mansion’s distinctive architecture earned it description as “castle-like” in coverage of the raid.
Xuan and Zhang’s operation, Mark Surrogacy, appears to have functioned without the oversight typical of licensed agencies in the state. California requires surrogacy agencies to meet various regulatory standards, including background checks and contractual protections for all parties.
The whereabouts and status of the 21 children following the arrests have not been disclosed. Child welfare authorities typically intervene in cases involving allegations of commercial exploitation of minors.
Krems’s defense strategy centers on two distinct claims: a scapegoated employee and constitutional protection for family size. Whether courts will view these as compatible or sufficient remains to be tested as the case proceeds.
The “nanny” referenced by Krems has not been identified by name, and no independent confirmation of this person’s role or flight has emerged. The attorney’s statement represents the sole account of this figure’s involvement.
Multiple law enforcement agencies participated in the coordinated Tuesday morning action, indicating the case had been under investigation for some period before the arrests. The timing of the raid, in early morning hours, follows standard practice for operations where authorities anticipate potential resistance or evidence destruction.
