Non-Human DNA Criminal Cases
Transcript of Non-Human DNA Criminal Cases
IN CRIMINAL CASES
Denver District Attorney
DNA Helps Game Officials Solve Cases
DNA sample taken at crime scene can lead to answers.
The DNA can be from that animal and from no other animal in the world.
Prosecutors' Latest Tool: Animal DNA
DNA Used to Catch Poachers
DNA has proved successful in prosecuting poachers of wild turkeys, turtles, alligators and other illegally hunted species.
DNA to Identify Contraband Animal Products -Valuable Ivory Elk Teeth
An elk was poached.
A warden contacted a man who had elk teeth.
DNA from the teeth matched the poached elk.
Disproving his claim that the teeth were from an elk found already dead.
Moose's DNA Dooms Poacher
A state wildlife officer began investigating after finding a moose skull that had been dug up by a bear.
The moose had been killed and a great deal of trouble went into concealing the crime.
A tip pointed them to a suspect and a search of his storage unit turned up a moose pelt and photos that placed him at the scene.
DNA tests confirmed the pelt belonged to the moose whose skull was found.
The poacher was ordered to pay an $11,391 fine.
DNA Stops a Man Poisoning Protected Animals
Game officials found several protected carnivores poisoned.
DNA from tainted meat found in the animals’ stomachs matched DNA from deer meat found in the suspect’s freezer.
Deer's Genetic Fingerprint Helps
Officers Nab Strange Poacher
Wyoming case - boy meets deer - deer hair on boy - boy gets in trouble for poaching.
DNA Used to Convict Egg Smuggler
When a smuggler was caught with eggs hidden in her bra, she smashed them.
Conventional identification became impossible.
DNA testing of egg membrane identified which protected birds they were from.
DNA Nabs Sea Turtle Egg Smugglers
Rare sea turtle eggs were being sold as aphrodisiacs by restaurants and grocery stores in South Florida.
Selling eggs from an endangered species is a federal crime.
DNA testing was used to track the eggs to Nicaragua enabling authorities to tack on federal smuggling charges.
Dog DNA Used in Investigation and Prosecution of Dog-Fighting
A dog-fighting DNA database helps establish ties among breeders, owners, fighting pit operators and the dog victims themselves.
The real money comes from breeding champion fighting lines.
A champion fighter can bring in up to $50,000 and a promising puppy can have a price tag of $5000.
Fighting-dog breeders pretend that they are just breeding pet dogs for the love of the breed and “don’t know nothin’ ‘bout no fightin’.” The DNA shows otherwise.
DNA Clears Man with Sheep Head
A man was accused of killing and decapitating an endangered big horn sheep.
He claimed that the skull found on his property was one he’d had for years.
DNA from the skull did not match the DNA from the carcass.
DNA Proves a Falcon Theft
A falconer claimed he found a juvenile goshawk.
DNA from the bird was compared to an old DNA profile of a bird from a nest which had been as part of an on-going research project.
The DNA profiles conclusively proved that the birds were one and the same.
The man was found guilty of taking the bird from the wild.
DNA Prevents Cockatoo Swap
A man had received the pet cockatoo as part of a divorce.
When he noticed the bird “had a different personality & was troubled” DNA testing was done.
DNA from a feather of the original bird did not match DNA from the current bird proving that the ex-wife had swapped cockatoos.
DNA Helps Save the Whales
The world's most voracious pirate-whaling market is losing its appetite for endangered whales due to DNA work.
There are whales now swimming which would have otherwise been under bubble-wrap in Japan's marketplace.
Whale meat for sale in Japan was traced back to the whale that was illegally killed in the North Sea.
DNA Used in Major Caviar Busts
A man smuggled 163 pounds of Caspian caviar into the U.S.
DNA testing is used to pinpoint the varieties of caviar.
He was the first U.S. smuggler convicted of violating the sturgeon protection laws.
Something Was Fishy
Three sushi restaurants in Florida were found guilty of selling sailfish in violation of federal law.
DNA testing confirmed that the "tuna” was indeed sailfish.
DNA Absolves a Man of Export Law Violation
Federal law prohibits the export of bear parts.
A man offering to supply bear gall bladders for export to Asia was investigated.
DNA testing showed that the gall bladders for sale were from pigs.
DNA Catches Killer Dog
DNA testing identified a dog that killed one miniature horse and maimed another.
Traces of blood with DNA identical to that of the dead horse were found along the rim of the dog’s water bowl.
DNA Clears Guard Dogs at Zoo
14 animals in a Hungarian zoo were killed in 1 week.
Zoo officials suspected they were the victim of dogfight training.
The zoo guard dogs were suspected.
DNA results confirmed that the killer was a single dog & all the guard dogs were excluded.
DNA Ties Escaped Tiger to Owner
A stray carnivore was believed to be walking in and out of the Chennai Zoo. Authorities closed the facility to the public.
A sample of the beast's fecal matter was DNA tested and identified as a leopard's.
Zoo authorities later trapped a 10-year-old leopard, which lived in the vast forests nearby and visited the zoo when she was in heat.
DNA Helps Capture an Unusual Zoo Visitor
A Bengal tiger escaped from a private facility in New Jersey; the owner claimed the tiger had come from a nearby safari park.
The DNA profile from the tiger matched DNA from a clump of fur found within the perimeter fence of the private facility.
The state was able to close the facility.
DNA Proves the Dog Ate The Will
A hungry terrier is being blamed for eating the last will of a woman who cut her family out of her $750,000 estate.
The remains of the dog-chewed paper were submitted to DNA testing.
Results showed that Daisey had wrapped her chops around the will.
Watch Your Step!
DNA From Dog Feces Used in Triple Homicide Case
He really stepped in it...
DNA from dog feces found on the sidewalk of the house where the killings occurred matched DNA in the dog feces on Stroud’s shoes.
The chance of randomly finding another dog having the same DNA was a one in 10 billion.
DNA Used to Stop Vandal Bears
Park Rangers at Yosemite National Park use DNA to ID bears that break into cars looking for food.
Most bears in the area have previously been captured & blood tests have been taken.
Bear fur from bear-damaged property is sent for DNA analysis.
DNA Used to Stop Deadly Bear Problems
DNA testing is used when bears have injured or killed humans.
When a hiker in Glacier National Park was mauled by a grizzly in 1998, scat found at the scene was genotyped.
The DNA evidence led to a mother and her cub.
Scientists believe they may have found proof of the Abominable Snowman in the form of a tuft of orange-yellow hair found on a tree in Bhutan.
British DNA researchers tested the hair and were unable to identify the DNA.
It is not from a human nor any known animal.
Deployed two dogs as weapons to attack the victim before he repeatedly stabbed and beat to the victim to death.
One dog, who was owned by Johnson, left a blood trail when he and his owner ran away from the scene. When police arrested Johnson, his victim's blood was on his hands and there was also blood from his dog on his body.
Saliva from the other dog was discovered on torn clothing found at the crime scene. DNA from both dogs was used as evidence and a dog DNA database was used to show that the probability of seeing the same DNA in another dog is less than one in a billion.
Johnson was found guilty of murder.
DNA From Deerjacking Leads to Marijuana Conviction
DNA found in drag marks at the scene where a deer was illegally shot matched DNA from drag marks in the suspect’s yard.
DNA results were used to obtain a search warrant for the suspect’s house.
Instead of deer meat, investigators found marijuana in the suspect’s freezer.
DNA Used to Prove A Restaurant Was Serving Illegally Caught Salmon
The DNA profile of the fish at the restaurant matched that of the profile of salmon caught by poachers.
The restaurant pleaded guilty, paid an $8,000 fine, and turned over the illegal salmon
DNA Resolves Dognapping Case
The crew of a Chinese fishing vessel was accused of stealing a woman’s dog after she saw the dog on their ship.
After comparing DNA from the dog’s mother & sister, it was proven that the dog was not the stolen dog.
DNA Testing & the Horse Insurance Industry
DNA is used, pre-purchase, to determine what is the lineage of an animal.
DNA ensures that the stallion semen used is from the stallion claimed.
Someone spending over $100,000 for a horse should invest the $100 for a DNA test.
DNA Links an Inhaler Filled With a Prohibited Substance to Race Horses

Human & Insect mtDNA Analysis from Maggots
mtDNA testing performed on the contents of a gut of a maggot that had fed on human tissue.
Used to ID both the human upon which the maggot fed and the species of the maggot itself.
Dispels the possibility that a larva collected from a victim had originally come from a non-human source, and therefore any estimate of the larva's age not useful for estimating the victim’s time of death.
Knowing the species of a larva helps in estimating the victim’s time of death.
Are there Big Cats killing deer in the UK?
Extensive DNA tests on two deer carcasses found near Woodchester Park and Dursley have drawn a blank on a big cat but point to a fox instead.
Angelo Monderoy - was found guilty of aggravated animal cruelty, burglary and arson in a case where he took a defenseless cat to an empty apartment and lit it on fire. DNA from a sample of the burnt tissue found in the apartment and DNA from the cat was a positive match.
DNA is used to identify the species of origin of items of evidence.
DNA is used to establish an animal’s gender.
Short tandem repeat (STR) DNA analysis is carried out for purposes of individual identification, assignment of population of origin and parentage determination.
Population identification has proven important in the prosecution of cases where an animal is being claimed as originating from one geographic region but is suspected to have been taken from another.
Parentage analysis is performed to determine if animals have been illegally obtained from wild stocks. Sibling Analysis is to determine sibling relationships between a number of animals thought to be from the same litter.
