An Arizona woman was mauled to death by a dog Friday and another man nearby was critically injured.
The Sierra Vista Police Department announced the incident in a press release on Saturday. Officers responded to a 911 call about a dog attack between Meadowlark Drive and Calle Del Norte.
"Officers arrived on the scene and found a dog attacking a male victim in the backyard of a residence on Calle Del Norte," police said in the release.
While the victim was being treated, officers found an 84-year-old woman with serious wounds in the alley behind a home and a second aggressive dog nearby.

"A second female victim was found in the alley behind the residence as a second dog returned to the same yard where the first attack occurred," police said in the statement.
Sierra Vista resident Helene Jackson was taken to Canyon Vista Medical Center but died from her injuries later that night. Officers said her dog, who was also presumably attacked by the other dogs, was found dead in the alley where she was found.
The injured man, Sam Sanches Jr., 53, was taken to Banner Medical Center in critical condition. Police said both of the violent dogs were killed by officers.
