Fredrick Allen Formigoni, 60, was shot and killed in his home on July 19, 2017, in Metcalfe, a small community near Greenville, Mississippi. A Mississippi State University graduate and lifelong farmer, Formigoni was a father of four and enjoyed hunting, fishing and cooking for his grandchildren.

The Washington County Sheriff’s Department reported few leads at first; after more than three months investigators say they made a breakthrough and arrested four people in connection with the homicide. Authorities charged Eugene Sanders, 31, and Jessica Fryrear, 30, with capital murder and later arrested 36-year-old Rodrick Payne and 24-year-old April Miller. Miller was already in custody in Indianola on an unrelated charge when she was charged in Formigoni’s death.
