Horrific images and video have been circulating on social media of a bear that was brutally killed in remote Sonora over the weekend.

Now an animal cruelty investigation is underway in Cumpas, Sonora, a two and a half hour drive south of Douglas.

On Sunday, local authorities put out a warning to residents to remain in their homes after a bear was spotted wandering through town, according to a statement. Orders were given to capture the animal alive. The same day, graphic images of a bloodied and apparently lifeless bear started circulating widely.

Authorities say that no city personnel fired their weapons or were otherwise involved in the death of the animal.

Sonoran Gov. Alfonso Durazo called for the state attorney’s office to investigate. On Tuesday, state attorney Claudia Indira Contreras said the investigation was underway, but that the bear’s body had yet to be found.
