The landfill search started yesterday after months of preparation. Police haven't yet said whether they've found anything related to Shockley's disappearance. However, they've released some photos of the search, which you can see below.
Shockley's been missing since October. Police have since determined that she's likely dead, and that her mother, Jerice Hunter, probably killed her.

Authorities say at least 40 people from agencies including the Glendale Police Department, the FBI, and the Child Abduction Response Team, will be at Butterfield Landfill in Mobile every day until the search is complete.
Investigators have narrowed down a 180-by-200-foot area of the landfill where they suspect Shockley's remains might be. The area is 20 feet deep, which amounts to about 6,000 tons of trash investigators will have to sift through.
