Oklahoma police raided Greater Wynnewood Exotic Animal Park after two of their cadaver dogs alerted their handlers of potential human remains located on the site.

The dogs that alerted their handlers are part of a filming episode by the Travel Channel, Ghost Adventures. Jeff Lowe, the current zoo owner, told Oklahoma’s KOCO-TV that the handlers believed that their dogs found remains due to their scents.

Just last month, Seattle police investigated the area after bags containing human remains were found near Elliot Bay’s shoreline. A month before, the police detained two people after an officer found human remains on a suitcase. Last year, another case of human remains in a suitcase was left in a creek on Southeast Indianapolis. The police confirmed the remains were not of an infant, and they are unsure of how long the remains were in the creek.

Netflix’s Tiger King: Murder, Mayhem, and Madness took place in the zoo now under Lowe. The former zookeeper Joseph Maldonado-Passage, known as “Joe Exotic,” had his life documented. He was convicted due to animal abuse and attempted murder in April 2019. He plotted to kill Big Cat Rescue chief executive officer Carole Baskin.

Last month, the court granted Baskin control of Greater Wynnewood Exotic Animal Park. They ruled that the property’s transfer was fraudulent. In a bid to avoid paying Baskin a previous $1 million trademark judgment, the property was transferred to Joe Exotic’s mother, Shirley Schreibvogel.

The remains found by the cadaver dogs turned out to belong to a small animal. Oklahoma’s Garvin County Sherrif told Oklahoma’s KFOR-TV. Taylor Adams confirmed this report in a post on Twitter. She tweeted, “EXOTIC UPDATE: The Garvin County Sheriff says no human remains were found on-site at the GW Zoo tonight. Instead, a small animal. He says the investigation is over. @kfor @joe_exotic.”
