Reporter Hannah Poling said a confidential source told her that a wildlife biologist and consultant for the federal forestry received hundreds of reports over the last several days from forestry workers discovering "hundreds of dead animals in Ohio's parks." 

Several labs across the country have received specimens of whole minks, deer, elk, worms and livers of such animals, and they are finding toxicities that are off the charts, the source said. 

"These highly toxic levels are the exact chemicals that were released from East Palestine. Wayne National Forest and Shawnee State Forest in Ohio, are downriver from East Palestine and are two parks where samples are from," the source continued. 

Meanwhile, the BBC reported: 

Nearly 45,000 animals have died as a result of a toxic train crash this month in an Ohio town, environmental officials have said.

 The figure from the Ohio Department of Natural Resources updates the initial estimate of 3,500 animals dead after the 3 February derailment.

The source also told the Ohio Star that Governor DeWine attempted to block scientists from entering state parks:

The governor and the railroad were blocking scientists from getting soil samples in East Palestine, but they were able to still grab some for testing. Likewise, the soils are highly contaminated," the source said.

The source claims that the Ohio governor only uses his own hand-picked scientists to "give him the results he wants."

"It is heartbreaking to me that politicians like DeWine make an issue like this political. It should not be. He should be doing all he can to protect people, animals and the environment and not just cover his own behind," the source added.
