On or about August 16, 2023, three children — 9-year-old Hillary Armendariz, 5-year-old Damaris Armendariz, and 2-year-old Matias Armendariz — were shot and killed by their biological father, 28-year-old Ruben Armendariz, in a quadruple murder-suicide at a home in northwest Oklahoma City near Melrose Lane and Rockwell Avenue. Their mother, 29-year-old Cassandra Flores, who was married to but separated from Armendariz, was also shot and killed. A family member who lived at the address discovered the victims and the suspect around 11:30 p.m. Flores and two of the children were pronounced dead at the scene; the third child died at a hospital. Armendariz was found with a self-inflicted gunshot wound to the head and later died at a hospital. Police believe he shot all four victims before turning the gun on himself.
