A 3-week-old was killed after one of her family’s three pit bulls attacked the baby girl while she was unattended with the dogs, according to reports.

Susannah Jean Murray was left alone in a bouncy for five minutes inside of her Michigan home when one of the dogs attacked her, according to authorities.

When an adult returned to check on the girl, she’d suffered severe injuries, including a bite to her head, which authorities said is what killed her.

One of the family’s pit bulls was then found with blood on its mouth, reports said.

Susannah was taken to the hospital and underwent surgery but she died hours later, according to reports.

Residents who lived in the Grand Rapids neighborhood told the Detroit Free Press that the dogs were a dangerous nuisance, calling them “mean and vicious.”

“I’d be scared, because when the dogs get out the fence, they used to chase us,” Hawa Abdi told the paper.

Police took all three dogs to be quarantined at the local animal shelter after the attack.

“The breed of a pit bull, by itself, is not enough to condemn it; any dog can bite. This serves as a critical reminder to never leave a child unattended around a dog,” Grand Rapids Police Department spokesman Sgt. Terry Dixon said.

No one has been arrested in connection with the baby’s death.
