California authorities are investigating one of the state’s most disturbing recent animal welfare cases after a search of Miranda’s Rescue Animal Sanctuary uncovered 117 dog remains, 21 dog skulls and hundreds of bones. The investigation has also expanded to examine what happened to more than 700 animals that cannot currently be accounted for.
The search at the sanctuary near Fortuna in Humboldt County has drawn national attention because investigators believe many of the recovered dogs had been shot. While no criminal charges have been filed, detectives say the inquiry is far from over as forensic examinations, adoption records and financial documents continue to be reviewed.
According to the Humboldt County Sheriff’s Office, investigators are examining allegations including felony animal abuse, animal cruelty, fraud and conspiracy involving Miranda’s Rescue Animal Sanctuary.
Search uncovers buried dogs and suspected evidence of shootings
The investigation reached a critical stage when detectives executed a search warrant at the sanctuary property in Fortuna, California.
Officials recovered the remains of 117 dogs, along with 21 dog skulls and hundreds of additional bones buried or scattered across the property. Investigators also documented canine remains found in open fields, many of which were in advanced stages of decomposition.
Veterinary forensic specialists later X-rayed 70 of the recovered dogs. Authorities said many of those animals contained bullet fragments, raising further concerns about how they died.
Investigators also located what they believe may have been a barn where dogs were killed. Nearby, officers recovered roughly 600 dog collars, which could become an important piece of evidence as they attempt to identify individual animals through microchips, shelter records and owner information.
More than 700 animals remain unaccounted for
Beyond the grim discovery of buried dogs, investigators are focused on another troubling issue.
Humboldt County Sheriff William Honsal said approximately 900 dogs had been transferred to Miranda’s Rescue since January 2025. However, investigators have only been able to verify 116 successful adoptions.
That leaves more than 700 animals whose whereabouts cannot currently be confirmed.
The sanctuary reportedly accepted dogs from owners and rescue organizations while charging rehoming fees ranging from $500 to several thousand dollars. Those financial transactions are among the reasons investigators are examining potential fraud alongside alleged animal cruelty.
Speaking about the investigation, Sheriff Honsal said authorities are “thinking worst-case scenario” while continuing to collect evidence.
How the investigation started
The case began after the Humboldt County Sheriff’s Office received a tip on April 26 alleging serious misconduct at the rescue.
Animal rights activist Jennifer Raymond later said she had heard repeated concerns about conditions at the sanctuary. She and another activist entered the property and reportedly unearthed eight dead dogs that appeared to have gunshot wounds to their heads.
Those remains were turned over to investigators, helping law enforcement obtain a search warrant that ultimately uncovered far more extensive evidence.
After documenting burial sites and collecting forensic evidence, investigators covered many excavation areas again, leaving the recovered animals in what officials described as their final resting place.
Why authorities have not shut the sanctuary down
Despite the discoveries, Miranda’s Rescue continues operating.
Officials say about 50 dogs, along with cats and birds, remain at the sanctuary.
Sheriff Honsal explained that California law does not automatically permit authorities to close a rescue facility simply because it is under investigation. Until criminal proceedings or other legal actions occur, the sanctuary is allowed to continue operating.
Officials emphasized that no criminal charges have been filed at this stage, although the investigation remains active.
Owner responds to the allegations
Sanctuary founder Shannon Miranda has strongly denied wrongdoing.
In a statement published on the organization’s website, Miranda said he has devoted more than 30 years to rescuing animals that other shelters could not accommodate.
He also defended Miranda’s Rescue as a no-kill organization while acknowledging that euthanasia may occasionally occur when an animal suffers from a terminal illness or presents a serious public safety risk.
Investigators are expected to compare those statements with veterinary records, intake logs, adoption files and forensic findings gathered during the investigation.
Why this investigation extends beyond one rescue
The case has renewed debate about oversight of private rescue organizations that receive animals from overcrowded shelters and private owners.
Animal welfare experts say rescue groups often depend on public trust, making transparent recordkeeping essential. Intake forms, veterinary reports, microchip registrations, transfer paperwork and adoption documentation can become critical evidence whenever questions arise about an animal’s fate.
Concerns about animal welfare enforcement have also surfaced in other investigations. Similar forensic work was highlighted in the investigation into a golden eagle found with 17 shotgun pellets in Scotland, where authorities likewise relied on physical evidence to determine what happened.

Detectives continue reviewing forensic evidence, financial records, shelter transfer documents and witness interviews before deciding whether the findings should be presented to prosecutors.
For hundreds of families, rescue organizations and former pet owners, the investigation remains deeply personal. Until every possible record has been examined, the fate of more than 700 animals remains one of the biggest unanswered questions in this expanding California animal sanctuary investigation.
