Twenty-one children, thirty-two cameras, and a house of horrors in Arcadia.

There is a particular kind of darkness that can hide behind closed doors in affluent neighborhoods, invisible to neighbors and unremarkable to the passing eye. This week, in a sprawling mansion in Arcadia, California, that darkness was finally brought into the light—and what authorities described was almost beyond comprehension.

Guojun Xuan, 66, and his wife Silvia Zhang, 39, were arrested Tuesday on multiple counts of child abuse, conspiracy to commit child abuse, and dissuading a witness. Prosecutors are seeking $100 million bail, citing the severity of the charges and the couple's flight risk .

The investigation began in May 2025 when a hospital reported that the couple's two-month-old infant had suffered a traumatic brain injury—the result of a nanny violently shaking the baby . When police arrived at the home, they found fifteen children ranging in age from two months to thirteen years, most between one and three years old. Another six children were located elsewhere. In total, authorities say the couple had at least twenty-one children, almost all born through surrogate mothers .

What investigators found inside the home, District Attorney Nathan Hochman described as a "house of horrors." The couple had set up three rooms they called "learning centers," where children spent hours each day sitting at desks under the supervision of nannies. An extensive surveillance system—more than thirty cameras—captured the nannies subjecting the children to daily beatings. In one video, Xuan is seen entering a room and telling a nanny to strike a child harder. In another, he joins the nanny in hitting the child .

The nannies were instructed "not to leave any physical marks on the children," according to prosecutors. When police arrived to investigate, the couple told the children to deny they had been beaten . One nanny, Chunmei Li, was charged in July with assault likely to cause death in connection with the infant's injuries, but she has not been arrested and is believed to have fled to China .

Prosecutors also allege the couple misled surrogates around the country. At least eight women came forward to say they were aggressively pursued by the couple to serve as surrogates and were given misleading or incomplete information about the family's situation. In one instance, Zhang represented herself as a single mother to conceive another surrogate. In another, the couple concealed from a surrogate until she was seven months pregnant that they already had sixteen other children .

Xuan's attorney, Mitchell Krems, has said his client's goal was to raise children who become productive adults. "Some who are wealthy might spend on jewelry or cars, but he is actually spending his resources to help his children become educated," Krems said .

All the children have been removed from the couple's custody. The investigation into their parentage and the full scope of the alleged abuse continues.
