The examination was prompted by public speculation that industry was somehow involved, but Schwantje also hasn’t found any evidence to support that claim. Previous tests showed that they weren’t suffering from any viruses, but also that they all had broken bones.

Although inconclusive, the province’s investigation has finished.
