Suspects in two, high-profile cases in Dickson County appeared in court Tuesday, where their attorneys sought a change in venue.
A change of venire was granted in both cases, meaning an outside jury will be brought in and the trial will remain in Dickson County.
Joseph Daniels has been charged with homicide in the case, while Krystal Daniels is charged with child neglect.
At one point, Joseph Daniels took the stand and requested he be transferred from Riverbend Maximum Security Prison.
Daniels claims he hasn't been able to see his family as much since he was moved from the Dickson County Jail. He also said his mental health has declined since he's been at Riverbend, adding that he's had suicidal thoughts.
However, a judge denied his transfer request.
His son, Joe Clyde, has been missing since April. Investigators said Joseph Daniels admitted to killing the boy, but isn't revealing where the body is located.
NewsChannel 5 has learned that there's another investigator in the mix, trying to find Joe Clyde.
David Mashburn has solved some high-profile missing persons cases across the country. He's now in Dickson County working this case alone as part of his non-profit Search for Me Foundation.
Steven Wiggins, the suspect accused in the shooting death of Sgt. Daniel Baker, also appeared in court.
The manhunt for Wiggins lasted several days, before he was found on the side of the road in Hickman County.
