A recent investigation looking into the allegations of child abuse of two adoptive parents has just taken a surprising turn.

In a news release shared by police earlier this week, it was revealed that police recently learned of the eight to ten-year-long disappearance of a teen girl named Kaya Centeno while investigating allegations of child abuse carried out by her adoptive parents. Centeno’s siblings — a brother who is aged 15, and a sister who is 17 — had reported that their parents had abused them. It wasn’t until the two children were taken into police custody that they told police that Kaya went missing from their family home in Rohnert Park sometime between 2010 and 2012. The siblings went onto tell the police that her disappearance occurred at the same time that they began to endure alleged emotional, sexual, and physical abuse by their adopted parents, Gina and Jose Centeno.
