Jury selection began Monday morning in Chattanooga's first federal death penalty case.
Prosecutors said jury selection could take up to a week in the case in which Rejon Taylor is charged in the 2003 murder of Atlanta restaurant owner Guy Luck at Collegedale.
Judge Curtis Collier is presiding over the case, which is expected to last six weeks.
The jury will not be sequestered.
If the jury finds the defendant guilty, it will be up to the panel to then consider whether he should receive the death penalty.
Co-defendants Sir Jack Matthews and Joey Montrez Marshall are set to testify for the government.
Steve Neff and Chris Poole are prosecuting. Defense attorneys are Lee Ortwein, Bill Ortwein, Leslie Cory and Howell Clements.
The case, which was switched from Hamilton County Criminal Court, was later ruled "death eligible" after being reviewed by the U.S. attorney general.
According to an earlier hearing in state court, one of the defendants said the plan was to let the victim out to find his way back to Atlanta, but he was shot after he "jumped" them on Aug. 6, 2003. The 51-year-old Luck was abducted at Buckhead in his white Econoline van.
