A devastating dog attack in Sierra Vista, Arizona, resulted in the death of an 84-year-old woman and left a 53-year-old man critically injured. The incident occurred on Friday, prompting a swift response from the Sierra Vista Police Department.

Officers arrived at the scene following a 911 call reporting a dog attack between Meadowlark Drive and Calle Del Norte. They discovered a male victim, later identified as Sam Sanches Jr., under attack in a residential backyard. While providing aid to Sanches Jr., authorities located Helene Jackson, the elderly woman, with severe injuries in a nearby alley. A second aggressive dog was also present at the scene.

Tragically, Jackson succumbed to her injuries later that evening at Canyon Vista Medical Center. Her own dog was also found deceased in the alley, presumably a victim of the attacking dogs. Sanches Jr. remains in critical condition at Banner Medical Center.

Police confirmed that both of the aggressive dogs involved in the attack were euthanized by officers at the scene. The three deceased animals are currently under the custody of the Sierra Vista Police Department’s Animal Control Office for further investigation.

Authorities are urging anyone with information regarding this incident to contact the Sierra Vista Police Department at 520-452-7500. The investigation is ongoing.
