Investigators uncover mass graves and decomposing animals at Northern California animal rescue

Investigators in Northern California are excavating a property where mass graves containing decomposing animals and missing shelter dogs were discovered. Over 700 dogs remain unaccounted for, with dozens recovered so far, many with microchips. The investigation, involving local and federal agencies, began after a neighbor found a burial pit with dogs shot, but no charges have been filed against the rescue's owner or staff.
