Investigation into deer deaths

Tribal officials are investigating a series of deer deaths and suspect hemorrhagic disease as a possible cause, according to the Billings Gazette and the Missoula Missoulian.

The reports, which cite tribal officials, indicate that the disease—likely epizootic hemorrhagic disease (EHD) or bluetongue—may be responsible for the deaths. Both outlets emphasized the suspicion rather than a confirmed diagnosis, noting that further testing is needed.

The Missoulian's coverage, authored by outdoors and environment reporter Sam Wilson, did not include additional details in the available text. The Billings Gazette carried the same basic information without further elaboration.

Hemorrhagic disease is a viral illness that affects deer, often transmitted by biting midges. It can cause internal bleeding and high mortality in affected herds, though it does not pose a threat to humans.

At this stage, no official confirmation has been provided by tribal authorities or wildlife agencies. The investigation is ongoing, and more information may emerge as test results become available.
