Her disappearance launched a massive search and made national headlines, but Grinstead was never found.
Despite an extensive investigation, no arrests were made in the case until February 2017. Duke was charged with her murder after an hours-long interview with the GBI during which he confessed, according to investigators.
During his trial, Duke said his confession was a lie. He claimed he was under the influence of drugs at the time and was scared of his former best friend, Bo Dukes. The jury apparently believed Duke.
Within days of Duke being arrested, Dukes was also charged in the case.
In March 2019, Dukes was sentenced to 25 years in prison for concealing Grinstead’s death, two counts of making false statements, and hindering the apprehension of a suspect. Dukes initially claimed he didn’t know anything about the disappearance and death. Months later, Dukes confessed. He didn’t kill Grinstead but helped dispose of the body, on his uncle’s property, according to evidence at his trial.
After Dukes killed her, according to Duke, the two burned her body in a pecan orchard owned by the Dukes family. Bone fragments were located in the area but were so heavily charred that scientists were unable to extract DNA samples.
