Moses, 28, was indicted last year on murder charges in connection with the deaths of Jadon Higganbothan and 28-year-old Antoinetta McKoy.
Their remains were found buried plastic bags by a plumber working in the backyard of a home in the 2600 block of Ashe Street last summer.
Along with Moses Jr., Higganbothan's mother 25-year-old Vania Sisk, 40-year-old Lavada Quinzetta Harris and 40-year-old Larhonda Renee Smith have been indicted on murder charges in connection with McKoy's death.
McKoy and Higganbothan lived with a polygamist religious group led by Moses known as the "Black Hebrew Israelites."
At a court hearing last year, Durham District Attorney Tracey Cline said Moses believed the boy was homosexual and that was unacceptable to his religious beliefs. She said Moses shot Higganbothan in the garage of a home on Pear Tree Lane in front of his mother.
Cline said investigators believe McKoy was killed because she tried to escape from the group and it feared she would tell police about the murder.
