The Brief Guojon Xuan and Sylvia Zhang were arrested on suspicion of conspiracy to commit child abuse after 21 surrogacy-born children were found under their care. Investigators uncovered the case after the couple delayed medical care for their two-month-old infant, who suffered a brain bleed from an assault by a nanny who has since fled to China. Authorities suspect the remaining children experienced severe verbal and physical discipline, though the exact motive behind housing so many children remains unknown. A California couple is facing serious charges following a law enforcement investigation that uncovered more than 20 surrogate children living in their home. Authorities intervened after a medical emergency involving an infant revealed a broader pattern of potential abuse and neglect inside the home. What we know: Deputies from the Los Angeles County Sheriff's Department's Special Victims Bureau arrested 65-year-old Guojon Xuan and his 38-year-old wife, Sylvia Zhang, on suspicion of conspiracy to commit child abuse. The investigation originated when Zhang brought the couple's two-month-old son to Children's Hospital Los Angeles, where medical staff discovered the infant had suffered a brain bleed and traumatic head injury. Arcadia police served a search warrant at the couple's home in the 600 block of West Camino Real and seized surveillance camera footage. The video showed a nanny employed by the parents violently shaking and hitting the baby, causing the infant to lose consciousness. Police stated that despite knowing about the assault, the parents waited two days to seek medical attention, only bringing the child to the hospital after seizures began. Following the initial response, the Department of Children and Family Services took protective custody of 15 children from the home, ranging in age from two months to 13 years old. Six additional children had already been moved to other residences, bringing the total number of children under the couple's care to 21. Arcadia police confirmed that all 21 children were born through surrogates before Xuan and Zhang as #fox2detroit #CrimeInTheD ®
