On a late Saturday morning in Hiram, Georgia, 18-year-old Katherine Mailne Castillo-Martinez, a Hispanic female, died after being shot inside a mobile home in the Nebo Ridge Estates community. Deputies responded to multiple 911 calls reporting numerous gunshots on June 24, 2023. Emergency personnel treated Castillo-Martinez at the scene and she was taken to a local hospital, where she later died.

Investigators say a dispute among several people at the mobile home preceded the shooting. Authorities identified 19-year-old Devon Michael Gandy of Dallas, Georgia, as the primary suspect and issued arrest warrants, warning he should be considered armed and dangerous and noting he has an identical twin brother who was not involved. Gandy surrendered to the Paulding County Sheriff’s Office and was arrested and charged with murder; he is being held without bond. Authorities indicated the investigation was ongoing and that more suspects or charges could follow.
