When court ended for the week on Friday, nine jurors had been seated.
The judge in the case says about 15 or 16 jurors will likely be picked, including three alternates.
McNeill is accused of raping and killing five-year-old Shaniya Davis in 2009.
He faces first-degree murder, first-degree rape of a child, first-degree kidnapping, human trafficking with a child victim, sexual servitude with a child victim, sexual offense of a child and indecent liberties with a child charges related to Davis' death.
He could face the death penalty if convicted.
Shaniya was given up by her mother, Antoinette Davis, to allegedly settle a drug debt.
Authorities said the girl's body was dumped just off N.C. Highway 87 near the Lee-Harnett County line.
The trial is expected to last six to eight weeks.
