Ada Ortiz, 44, was shot dead in her Allentown, Pennsylvania, home on the evening of December 29, 2023, along with her 1-year-old grandson, Sebastian Serrano. Both victims were struck multiple times in the living room; the Lehigh County Coroner ruled their deaths homicides by multiple gunshot wounds.

Ada’s husband, Leandro Ortiz, was in the kitchen preparing food for the children when he heard the gunfire. He reportedly pushed the shooter out of the house and was shot in the upper chest while protecting a 7-year-old grandchild; he was hospitalized and expected to survive. Investigators identified 43-year-old Gabriel Cartagena as a suspect and charged him with two counts of criminal homicide, attempted homicide, aggravated assault, burglary, and illegal possession of a firearm. After a trial in March 2026, a jury found Cartagena not guilty on all counts. The killings of Ada Ortiz and Sebastian Serrano remain unsolved.
