Police in the Phoenix suburb of Glendale say Tuesday that the search of the landfill will begin within the next few weeks.
Investigators say 5-year-old Jhessye Shockley was killed and her body was dumped in a trash bin across town before her mother reported her missing on Oct. 11.
Shockley's mother was arrested in November on suspicion of child abuse related to the girl but was released from jail day later after prosecutors said they wanted to investigate further.
Detectives believe the girl's body is in the landfill and the search could take several weeks.
