A new Glendale Police report indicates the woman drove Jhessye Shockley's mother to a Tempe Dumpster.
Investigators say the woman told them that Jerice Hunter had placed a large, heavy suitcase with a foul smelling odor into the trash.
The incident occurred about a week or two prior to Jhessye's disappearance.
The little girl is presumed dead.
Hunter is now behind bars in connection with her daughter's murder.
