A Detroit woman was attacked and mauled to death by her own pit bull in front of her house on July 16.
Elizabeth Rivera, 71, died of a crush injury to her neck. The coroner ruled Rivera's death an accident following an autopsy, reports Detroit Free Press.
According to Detroit Police Sgt. Michael Woody, Rivera's pit bull bit her in the neck, severed her jugular vein, and mauled her on the ground. Rivera's granddaughter discovered her body, WDIV reports.
There were four dogs in the house. It is currently unknown if all four were involved in the attack or if it was just one. All four dogs were placed in an upstairs room until Animal Control personnel secured the scene. The dogs were then taken into custody for further testing.
A spokeswoman for the Detroit Health Department said she was unable to provide more information about the other dogs due to the pending investigation.
"My heart just goes out to them and their family," neighbor Saira Barrera said after the incident.
"We have no idea and even family members are baffled," said Captain John Serda of why the dog attacked, reports WDIV. "I feel so bad for the family members to have dogs that belong to your family do something like this is beyond comprehension."
The case bears a resemblance to a case in Shaker Heights, Ohio in 2015. In that case, 71-year-old Annie Williams was mauled to death by a pit bull when she went to visit family members.
