A Tucson family home was the scene of a fatal shooting on August 11, 2012. Seventeen-month-old Richard Rosovich Jr. and his 4-year-old sister Emma Rosovich died of gunshot wounds; Richard was found dead at the residence and Emma was critically injured, later dying at a hospital.

Police say the children’s mother, 25-year-old Perla Morales, reported the deaths and was treated for non-life-threatening self-inflicted injuries before being taken into custody. Investigators say an argument with Morales’s boyfriend preceded the shootings, and Morales was later arrested and charged with two counts of first-degree murder after admitting to police that she shot her children. No prior reports of abuse or neglect with Child Protective Services were found.

If anyone knew the Rosovich family or has information about what happened that day, please share what can help the ongoing record.
