SAN JOSE, Calif. (KRON) -- The accused killer of 6-year-old Jordan Cam Walker has been found mentally competent to stand trial. Jordan was one of three children who were allegedly murdered while they were under the care and custody of the Santa Clara County Department of Family and Children’s Se rvices within the past three years, the district attorney said. Jordan's uncle, 29-year-old Nathan Edwards Addison, is charged with murdering his nephew and grandmother, Delphina Turner, in their San Jose home. For most of 2025, Addison was locked in a state hospital undergoing treatment for mental illness and the criminal case against him was suspended, court records obtained by KRON4 show. A Santa Clara County Superior Court judge found that Addison was incompetent to stand trail in January of 2025. He was ordered to receive involuntary anti-psychotic medication.

Jordan and his 71-year-old great-grandmother were found dead inside their San Jose apartment on Parkmoor Avenue on August 4, 2023. The killer stabbed the victims to death the night before, cleaned up the crime scene, and fled before police arrived, investigators said. Surveillance video recorded Addison destroying evidence at a nearby VTA train station, according to court documents. Addison's mother told detectives that her son was most likely responsible for the double homicide. Addison had a lengthy criminal record, including arrests for resisting arrest, assaults, and burglaries. He was released from jail on June 29, 2023. Nathan Addison (SJPD mugshot) Six-year-old Jordan was living with his great-grandmother leading up to the double homicide because he was placed there by the Department of Family and Children’s Services' foster home system, prosecutors said. According to a wrongful death lawsuit previously filed by family members, Child Protective Services agents placed the boy in a dangerous home living environment despite numerous warnings. Little Jordan was removed from his mother’s care after he brought a bag of methamphetamine to school, the suit states. When he was placed in his great grandmother’s home, neighbors saw Jordan left alone outside for long periods of time, attorneys claim. "Jordan was frequently seen on neighbors’ Ring cameras riding his bike at two and three o’clock in the morning, sometimes multiple nights in a row. The apartment was described as an endless revolving door of different drug users and homeless people — both short term and long term visitors, including Nathan Addison, Jordan’s maternal half-uncle," the lawsuit states. Outrage against the county's child welfare agency reignited earlier this April when a 2-year-old boy, Jaxon, was allegedly raped and murdered in his new foster home in San Jose. Jaxon Police officers found Jaxon unconscious in his crib on Easter Sunday suffering for fatal injuries. Prosecutors said the toddler’s suspected killer was a teenager who is Jaxon’s biological cousin and also his foster brother. The teen lived in the same home where Jaxon was placed by DFCS, officials said. Jaxon's foster brother was charged with murder in the juvenile court system. He recently turned 18, and District Attorney Jeff Rosen is fighting to transfer the case from juvenile court to adult court. Addison is scheduled to appear in court on May 8 to enter a plea. He remains in custody without bail. ...read more read less
