A California couple have been accused of running a suspected baby surrogate-fueled human trafficking ring that involved at least 21 children.

Guojun Xuan, 65, and Silvia Zhang, 38, were taken into custody in May on charges of felony child endangerment after officers arrived at their $4.1 million residence in Arcadia, following reports about a two-month-old who had suffered a severe head injury.

Inside, they found 15 children between the ages of two months and 13. Another six children had also been moved to other homes. 

Among the 21 children present, 17 were younger than three years old. The children, who were believed to be born from surrogate arrangements, were placed under the care of the Department of Children and Family Services.

Xuan and Zhang faced charges of child endangerment and neglect concerning the injured infant and were subsequently released. However, they have not faced charges relating to the supposed surrogacy activities.

Cops also issued an arrest warrant for their nanny Chunmei Li, 56, alleging that security cameras inside the home revealed Li was ‘verbally and physically’ abusing the children. 

Although having dozens of children through surrogates is not illegal, officials said they are investigating the startling find inside the home. 

Kallie Fell, executive director of the nonprofit Center of Bioethics and Culture, told ABC7 that while the couple may not have broken the law by having so many surrogate children, the situation ‘smells of trafficking.’

Zhang (pictured) and Xuan allegedly had 15 children in their home aged between two months and 13-years-old, and six other children had also been moved to other homes

Security cameras inside their home (pictured) allegedly showed the couple’s nanny was abusing the children, and she is also being sought by cops 

It is unclear what the couple do for work, with public records showing they are connected to a number of investment firms.

Arcadia police Lt. Kollin Cieadlo said that the couple ‘took legal guardianship of those kids’ after they were born through surrogates, before Li allegedly abused the children as their nanny. 

‘The discipline, both verbally and physical, was severe to the point where it supported the beliefs that child abuse was occurring inside the home Cieadlo said. 

The Arcadia police said the FBI has joined its investigation into a suspected mass-surrogacy operation owned and ran by Xuan and Zhang. 

Kayla Elliot, one of the surrogate mothers hired by the couple, said she believed that they were clients of a surrogate agency. 

‘It’s horrific, it’s disturbing, it’s damaging emotionally,’ she told ABC7.

Kayla Elliot, one of the surrogate mothers hired by the couple, said she believed that the couple were clients of a surrogate agency, and told her they only had one other child 

Elliot said she is now hoping to regain custody of the child she bore for the couple, and described the allegations as ‘horrific, disturbing, (and) damaging emotionally’ 

Elliot said the couple told her they only had one other child, and is now hoping to get custody of the child she bore for them. 

‘These agencies, we’re supposed to trust them and follow their guidance and come to find out this whole thing was a scam, and the parents own the agency – that was not disclosed at all beforehand,’ she added. 

Fell, who is working with Elliot, said that the surrogacy industry is unregulated, and oftentimes, ‘anything goes.’ 

‘And these clinics, these agencies are not regulated by any governing body,’ she said. 

‘That to me smells of trafficking… What are the intentions of having that many children at home through these assisted reproductive technologies?’
