The cause of death of multiple bears that were discovered in a Pennsylvania church parking lot has been revealed.

The West Wyoming Borough Police Department was called to St. Monica’s Parish to investigate the discovery of three dead bear cubs and their nearly 300-pound mother, the department said in a Facebook post.

The department called in the Pennsylvania Game Commission and the animal’s deaths were labeled as suspicious.

The commission asked the public for help via Facebook to find out what happened to the bears.

There were no “signs of bullet wounds or external trauma” to the animals.

“We consider the deaths of these bears highly suspicious,” Game Commission Northeast Region Law Enforcement Supervisor Mark Rutkowski said. “Toxicological testing will be performed in an attempt to determine a cause of death.”

The Pennsylvania Game Commission revealed on Facebook the bears likely cause of death: poisoning.
