On August 21, 2015 in Memphis’s Nutbush neighborhood, 29-year-old electrician Ronnie Joe Winborn and his 59-year-old mother, Laura Winborn, were shot to death inside their Vivia Avenue home. Two visitors, Derrick Smith and Robert Beman, had come to the house to look at guns Ronnie owned; the visit turned deadly. Ronnie was found in his bedroom with five gunshot wounds; his mother was found in the kitchen with eight.

Ronnie’s two young children, ages 3 and 5, witnessed the killings and escaped to a neighbor’s house to get help, telling them their daddy and nana were dead. The investigation led to the arrests of Derrick Smith and Robert Beman. Both men later entered plea agreements: Smith pleaded to two counts of facilitation of first-degree murder, and Beman pleaded to two counts of second-degree murder. A judge sentenced each to 30 years; Beman’s term was imposed with no possibility of parole.

If anyone knew Ronnie, Laura, or the circumstances around that visit to the Nutbush home, any additional information could still be important.
