The three-week-old girl, Susannah Jean Murray, had been placed in a bouncer by her mother, who then went outside onto the front porch of their Michigan house with a few other friends.
Police said the baby was found less than five minutes later badly mauled by at least one of the three pit bulls.
"When the incident occurred one of the three pit bulls had blood around its mouth. The other two did not," Officer Terry Dixon told WWMT.
Sadly, after seven hours of surgery, the little girl passed away from a severe bite to the head.
All three of the dogs have been removed from the home and quarantined.
