August 31, 2026 · North Rose, New York

New evidence of alleged criminal cruelty at Marshall BioResources
is now in the hands of New York authorities.

A criminal referral prepared by former federal prosecutor Bonnie Klapper, on behalf of the Coalition to Save the Marshall Dogs, asks Wayne County District Attorney Christine Callanan and Wayne County Sheriff Robert Milby to open an immediate criminal investigation into Marshall BioResources and, on confirming the violations it describes, to prosecute. The full letter and its exhibits are published below.

What happened

Evidence was submitted to New York authorities.

Marshall BioResources breeds dogs for laboratories at its facility in North Rose, New York, and is the largest supplier of dogs for experiments in the United States. On August 31, 2026, a criminal referral documenting alleged systemic violations of New York’s animal-cruelty laws at that facility was submitted to Wayne County authorities.
The referral was drafted by Bonnie Klapper, a former federal prosecutor who spent her career prosecuting violent drug cartels, on behalf of the Coalition to Save the Marshall Dogs. It rests on video and photographic evidence taken inside Marshall, the sworn opinion of a veterinary expert, statements from a whistleblower who worked there, and the USDA’s own inspection records.
Everything described on this page is an allegation contained in that referral and the material supporting it. None of it has been adjudicated, and Marshall BioResources has not been charged with a crime. The referral asks the authorities to determine whether it should be.

The allegations

What the evidence describes.

Improper killings

Barbiturate injected into the abdomen of conscious dogs

The referral alleges that a whistleblower who worked at Marshall was assigned to kill dogs by lethal injection, frequently alone and with no veterinarian present, injecting the solution directly into the abdomen. The dogs were fully conscious and had been given no sedative or anesthetic. According to the whistleblower they did not die quickly or quietly: they screamed, thrashed, and struggled in what appeared to be extreme pain, in the whistleblower’s words as if they were being “burned alive from the inside.” One dog who could not be muzzled was held down by a supervisor’s foot on his neck so the injection could be given.

A death during “mask” training

A dog died on the table

The referral describes inhalation “mask” training on a five-day schedule, escalating from five minutes in a harness to fifteen minutes with a tight-fitting mask sealed over the snout. One dog urinated and defecated in panic, thrashed and rolled — the whistleblower called it an “alligator roll” — and became tangled in the harness. The whistleblower tried to remove the mask; the dog died on the table.

Violent handling

To move thousands of dogs quickly, the referral alleges, employees threw them into transport cages “like a frisbee,” and the dogs’ heads snapped against the backs of the cages.

Concealment from inspectors

According to the whistleblower, Marshall usually had advance notice of USDA inspections, employees would “panic clean” the facility before inspectors arrived, and the mask training was not performed while inspectors were present.

Puppies smothered in food pans

In buildings with barely any heat, the referral alleges, puppies would lie down in the warm wet-food pans to stay warm and were smothered or suffocated in them. The veterinary expert report records a photograph taken inside the facility showing a dead puppy in a metal feeding pan encrusted with caked food.

Healthy dogs killed for appearance or grade

The referral alleges that many of the dogs the whistleblower was directed to kill were healthy — culled for traits with no bearing on health, such as blue eyes or a significantly kinked tail, or because a mother dog was “done being bred.” The bodies were bagged and taken to an incinerator, where the whistleblower saw them stacked in piles, on at least one occasion taller than the whistleblower, who is about five feet nine.

The ask

What the authorities are being asked to do.

The referral is addressed to Wayne County District Attorney Christine Callanan and Wayne County Sheriff Robert Milby, the two offices with jurisdiction over the North Rose facility. It asks them to open an immediate investigation and, upon confirming the violations it describes, to prosecute.
New York Attorney General Letitia James is the other office with the standing to act on conduct of this kind, with statewide reach and the resources to investigate a company of this size.
The referral charges violations of three sections of New York’s Agriculture and Markets Law. They are short, public, and summarized below.
