Forty-two-year-old Michael Landrum from Linden and 22-year-old Jeffrey Napier from Lisman are both charged with the murders of 52-year-old Ida Little and her three-year-old granddaughter, Mikaila.
Last August the two were found shot to death in Little's home in Linden. Mikaila was Landrum's daughter.
If found guilty, Landrum and Napier could face the death penalty or life in prison. Both remain in jail.
