Feds Unearth Bullet-Riddled Dog Corpses, 600 Collars Near Mass Graves At Rescue Sanctuary

Investigators uncovered more than 100 dog bodies in various stages of decomposition, along with canine skulls, hundreds of additional bones, and evidence that many animals were likely shot before being buried, as authorities deepened a criminal investigation into Miranda's Rescue in Humboldt County, where hundreds of animals remain unaccounted for.

Federal, state, and local investigators returned this week to the 50-acre sanctuary, using ground-penetrating radar and excavation equipment to search suspected mass graves. They executed a second search warrant for evidence related to alleged animal cruelty, fraud, theft, and conspiracy.

According to the Humboldt County Sheriff's Office, investigators recovered 117 intact canine remains from two burial sites, along with 21 canine skulls, hundreds of additional bones, six loose microchips, and more than 600 dog collars found inside a barn investigators believe may have been used to kill dogs.

USDA and forensic veterinarians conducted on-site examinations of 70 of the recovered dogs. X-rays revealed bullet fragments in many of the animals, and investigators preliminarily determined that gunshot wounds caused the deaths of many of them, according to the Humboldt County Sheriff’s Office Major Crimes Division.

The remaining 47 dog remains were collected as evidence and will undergo additional forensic examination. Most of the recovered dogs were microchipped, and investigators are analyzing those records to identify the animals and determine where they came from.

Investigators also located additional canine remains elsewhere in the field. However, many had decomposed so extensively that, after consulting with prosecutors, authorities determined excavating them would provide little additional evidence. Instead, investigators documented the location and condition of the remains before covering the site and leaving them undisturbed.

Humboldt County Sheriff William Honsal said the investigation now extends well beyond Humboldt County and includes shelters throughout California and Hawaii.

"This is a fraud investigation as well as an animal cruelty investigation," Honsal said during a recent press conference.

Records reviewed by investigators show shelters across California transferred more than 900 animals to Miranda's Rescue since January 2025. Authorities have verified the adoption of only 116 animals.

"We have 730 animals that are unaccounted for," Honsal said.

The case has exposed a little-known part of California's animal welfare system: private rescues that accept animals from overcrowded public shelters, often for transfer fees, while operating outside direct government oversight.

The Humboldt County Sheriff's Office began investigating Miranda's Rescue in April after two animal welfare advocates reported that dogs transferred from shelters across California may have been killed and buried instead of adopted. According to a search warrant affidavit, one advocate purchased neighboring property, installed trail cameras, and captured footage that appeared to show dogs being dumped into a mass grave. The two advocates later entered the property through an opening in a fence, discovered dead dogs, and led deputies to the burial site.

According to the affidavit, the women scanned the dead dogs' microchips, determining one of eight slain dogs — Zora — was transferred from Oakland Animal Services on March 31, 2026.

Shannon Miranda, who runs the rescue, had texted Oakland shelter officials to report that Zora had been adopted, according to investigators and Oakland Animal Services officials.

Investigators confirmed through a microchip that Zora was among eight dogs found in a pile of deceased animals. Because of blood and dirt on the remains, investigators were originally unable to determine whether Zora had suffered a gunshot wound.
