Martinez called 911 from her Loganville home early on the morning of July 6. When police arrived, they found Martinez with a slashed wrist, 9-year-old Diana Romero suffering from multiple stab wounds, and five dead: 33-year-old Martin Romero, 2-year-old Axel Romero, 4-year-old Dillan Romero, 7-year-old Dacota Romero and 10-year-old Isabela Martinez.

Martinez was detained by police and charged with multiple counts of murder and aggravated assault later that day. Police believe the stabbings occurred between 2 a.m. and 4 a.m. on July 6.

Martinez had fallen into a deep depression in the months before the stabbings, neighbors told the AJC. Her father had died and she was unable to attend his funeral in Mexico.

Martinez’s attorneys did not return phone calls from the AJC before the Monday morning hearing.
