On August 14, 2013, a family dispute in south Oklahoma City ended in a deadly outbreak of violence that killed four relatives inside their home. One-year-old Amario Dominguez was among the victims; the others were his mother, 34-year-old Rebecca Cizek, his 16-year-old sister, Catherine Cizek, and his grandmother, 57-year-old Sallie Green.

Investigators identified and arrested Daniel Green, the brother of Sallie Green and the uncle of Rebecca and Catherine Cizek, and charged him in connection with the four deaths. The close family ties between victims and the accused made the case especially traumatic for the neighborhood and surviving relatives.

If anyone knew the family, the household, or has information about the events leading up to that night, please share what can help the investigation.
