"Three deer have been found dead so far in the park area near Joshimath. Two of them seem to have died natural deaths but there is something suspicious about the death of one. We have sent their samples for testing to Indian Wildlife Institute," NNP DFO Rajiv Dhiman said.
Whether they died of some infectious disease will be known only after we receive the IWI report, he said.
Park sources requesting anonymity said there is a strong possibility of the deer dying of an infectious disease as they had died in quick succession.
