On June 6, 2016, a concerned family member checked on 49-year-old Rhonda Bishop-Dukes and her spouse Brenda Dukes at their Matthews Road home in Millington, Tennessee, and found both women dead. The case was investigated as a double homicide.

Investigators focused on a neighbor across the street, 46-year-old Michael Cullum. An arrest affidavit says Cullum confessed to shooting both Rhonda Bishop-Dukes and Brenda Dukes and that he took painkillers from the home after realizing the initial gunshots had gone unnoticed. Cullum was charged with first-degree murder in the perpetration of a robbery; the affidavit also notes a prior criminal history including burglary, theft and robbery.

The killings left the community shaken. If anyone knew Rhonda or Brenda, or has information about their lives or the events leading up to June 6, 2016, please come forward.
