Mayes' body had been with the Mississippi State Medical Examiner's Office since early May, when he killed himself. The body was picked up from there and delivered to the university's forensic department last week, said Mark Golding, medical examiner in Union County, Mississippi.
Mayes' body will not be identifiable to students because each body is assigned a number, CNN quoted William Bass, a retired professor at the school as saying.
Authorities allege that Mayes, 35, killed Jo Ann Bain, 31, and her eldest daughter, 14-year-old Adrienne, on April 27 at their home in Whiteville, Tennessee. He then abducted Bain's younger daughters, 12-year-old Alexandria and 8-year- old Kyliyah, who were missing for two weeks.
After being cornered in Mississippi by authorities, Mayes shot himself in the head and died. The girls survived.
Both his mother, Mary Frances Mayes, and ex-wife, Teresa Ann Mayes, are accused of helping Mayes.
