Ana Estevez’s 5-year-old son, Aramazd “Piqui” Andressian Jr., was murdered by his father, who was in a contentious custody battle with Estevez. After a day at Disneyland in April 2017, Aramazd Andressian Sr. allegedly took the young boy to a wooded area near Lake Cachuma, CA, and suffocated him, leaving his body propped against a tree. It was months later when Andressian Sr. confessed to murdering his own son and the child’s body was discovered.
