DULUTH-The Lake Superior Zoo continued to clean–up on Thursday after 13 of their animals died during flooding.
Employees say a culvert running underneath Grand Avenue was likely damaged - creating massive flooding during the unparalleled rainfall.
But People for the Ethical Treatment of Animals (PETA) says the zoo should have been more prepared to rescue their animals and sent a letter to Duluth's city attorney calling for criminal negligence charges.
Zoo officials say the group does not understand workers' relationships with the animals and need to look again at the severity of the storm.
"I think they'd have a better understanding of the situation and they wouldn't be so quick to make allegations that we couldn't do what we could with what we had," Keely Johnson, a Zoo employee, said.
Duluth City Attorney Gunnar Johnson has confirmed that he will not file charges against the Lake Superior Zoo citing the zoo's recent accreditation and the record-breaking flooding.
