Baby Doe

Rachelle Bond, the mother of 2-year-old Bella Bond, and Michael McCarthy appeared in court for an emotionally charged arraignment.

McCarthy is charged with killing Bella, whose body was found by a dog walker on Deer Island in June. Bond, who wore a gray zip-up sweater with the hood up in court, is charged as an accessory after the fact. Both are charged with unlawful disposal of human remains.

Joseph Amoroso said before court that he came to support 2-year-old Bella Bond, the daughter he never met.

Michael McCarthy, 35, is charged with murder. Bella's mother, Rachelle Bond, 40, is charged as an accessory after the fact. They are to be arraigned in Dorchester District Court in Boston.

Amoroso said Bond told him that McCarthy punched Bella in the stomach over and over again until she stopped breathing.

The image has attracted a staggering 45 million views on Facebook as investigators try to identity the child whose remains were found on a Boston Harbour beach nearly two weeks ago.

The mystery of Baby Doe began on June 25, when a woman walking her dog on the western shore of Deer Island called 911 and reported finding a trash bag containing the girl's body. The child was wearing white leggings with black polka dots. Inside the bag with her remains was a zebra-print blanket.
