Officers discovered 51-year-old David Green, Jr.'s body dismembered and stuffed in a freezer inside his home on Ray Road on October 6. He was reported missing on Sept. 1.
Green's live-in girlfriend, 41-year-old Wendy Edmond Green, is charged with his murder along with his children: 17-year-old Alexis Green and 15-year-old David Green, III.
Warrants released Wednesday suggest the children gave investigators incriminating statements that place them and their mother at the scene of the crime the night before the murder and the morning of the murder.
Authorities have said they believe all three planned the murder, participated in the crime, and then cleaned up the scene to conceal the killing.
The warrants say authorities collected hair, blood and saliva samples from both Wendy and Alexis Green.
They plan to compare their DNA with traces of evidence they found at the scene and in two of the victim's vehicles.
