Stuhr believes the animals fell victim to a lightning storm that passed through July 30 or 31.
"The lightning actually knocked out our server in the Stuhr Building, so there must have been multiple strikes,' said Chris Hochstetler, the museum's executive director.
A couple of days later, staff members discovered that one of the bison had died. The day after that, the other one passed away.
A veterinarian who treated the animal said a bison struck directly by lightning usually dies instantly. It's also very common that if another bison is within 30 feet, he will die a couple of days later.
A nearby strike scrambles the animal's neurological system and heart. "They will succumb to that within two or three days, which is exactly what happened," Hochstetler said.
